13.5.3

What's New in Aspire 13.5.3

Patch release for Aspire 13.5 that fixes Dashboard Graph view crashes for resources with multi-path icons and restores missing public URLs for DevTunnel resources.

🐛 Fixes

• 📊 Dashboard Graph view could crash for Azure Blob resources — Resources such as those created with AddBlobs use icons containing multiple SVG paths, which caused an XML parsing exception and broke the dashboard circuit. The graph now combines multi-path icons correctly. Regression introduced in 13.5. Fixes #​19489. (#​19585, backport of #​19579, @​sebastienros)

• 🌐 DevTunnel public URLs were missing from the Dashboard and MCP snapshots — DevTunnel port resources could report Running and Healthy while showing no public URLs. Proxyless port allocation is now limited to compute and container resources, allowing DevTunnels to publish their actual public endpoints. Regression introduced in 13.5. Fixes #​19496. (#​19625, backport of #​19590, @​karolz-ms, @​danegsta)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.5.3

13.5.2

What's New in Aspire 13.5.2

Patch release for Aspire 13.5 that removes an unused native helper binary from the Windows CLI archives so 13.5 servicing releases stay publishable to WinGet.

🐛 Fixes

• 🪟 Windows CLI archives shipped an unused ~4.9 MB hex1bpty.exe — The Windows CLI archives (aspire-cli-win-{x64,arm64}-*.zip) bundled Hex1b's out-of-process PTY host, which Aspire never executes (DCP owns every pseudo-terminal Aspire surfaces). Besides the wasted download, the extra unexplained executable stalled the WinGet publish, since every binary in the archive goes through executable and malware validation. A build-only MSBuild target now drops the file from the CLI publish output; Unix native assets are unaffected. Regression new in 13.5.

13.5.1

What's New in Aspire 13.5.1

Patch release for Aspire 13.5 fixing a TypeScript/Java polyglot AppHost compatibility regression when running the 13.5 SDK under an older (13.4.x) CLI, plus a DCP update and release-pipeline housekeeping.

🐛 Fixes

• 🍎 Polyglot AppHosts could crash on startup on macOS — On macOS, polyglot (TypeScript/Python/Java/Go/Rust) AppHosts could crash during startup due to an interaction between how DCP's Go runtime forks detached processes and how .NET Native AOT installs its signal handlers. Updated DCP (Developer Control Plane) to 0.25.13 to resolve the crash. ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp microsoft/aspire#19528))

• 🔗 Polyglot AppHosts on the 13.5 SDK crashed under an older CLI with MissingMethodException — A TypeScript or Java AppHost built with the 13.5 SDK failed to start when launched by an older (13.4.x) CLI, because the newer codegen called Aspire.TypeSystem members that don't exist in the CLI's older contract. Code generation now probes for these additive capabilities before using them, so older CLIs skip only the unsupported feature and startup succeeds. Regression introduced in 13.5 by #​19365. Fixes #​19503. ([#​19524]([release/13.5] Preserve TypeSystem compatibility with older CLIs microsoft/aspire#19524), backport of #​19506, @​adamint)

🏷️ Housekeeping

• 📦 Updated DCP (Developer Control Plane) to 0.25.13 ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp microsoft/aspire#19528))

• 🔧 Restored WinGet publication using .NET 9 wingetcreate ([#​19509]([release/13.5] fix(release): Restore WinGet publication with .NET 9 wingetcreate microsoft/aspire#19509))

13.5.0

Aspire 13.5.0

Aspire 13.5 is a developer-experience release focused on a richer, more interactive AppHost, closer C# and TypeScript parity, sharper tooling, more flexible deployment modeling, and a broad set of runtime-stability improvements.

Highlights

• 💬 Richer AppHost interactions — The Interaction Service now works across C# and TypeScript AppHosts with stable prompts and dynamic inputs, file uploads, progress dialogs, notifications, and user-defined resource command arguments that surface as dashboard controls and CLI options.
• 🖥️ Interactive terminal sessions — The experimental WithTerminal() API lets resources host REPLs, shells, TUIs, and other interactive programs directly in the dashboard, with an opt-in aspire terminal CLI command for attaching from your shell.
• 🌐 TypeScript AppHost is generally available — Polyglot AppHosts no longer require the ASPIREATS001 experimental diagnostic and gain custom health checks, container file copying, HTTPS developer certificates, faster startup, and several reliability fixes that further close the gap with C#.
• 🛠️ CLI installation and reliability — The Aspire CLI is available through npm and Nix alongside Homebrew, WinGet, mise, and NuGet. New C# AppHosts enable the CLI bundle by default, while aspire stop --force, aspire update --migrate, aspire doctor, docs search, signal handling, and stale-socket cleanup all improve day-to-day workflows.
• 🎨 Refreshed dashboard — The dashboard adopts official Aspire branding and a new accessible design-token system, with timestamp and exact numeric telemetry filters, console-log text search, clearer reconnect and health-check experiences, and correct telemetry streaming while filters are active.
• 💻 Rebranded VS Code extension — The extension is now named Aspire and adds an in-editor dashboard, Bun and MAUI debugging, resource commands in the tree view, discovered AppHosts, improved parameter handling, and more efficient workspace discovery.
• ☸️ More expressive deployments — Kubernetes and AKS gain first-class persistent volumes, Azure Container Apps adds deterministic unique resource naming, Azure environments support delegated subnets, and Docker Compose can publish Blazor gateways and configure shared memory.
• ☁️ Expanded hosting integrations — Azure resources can be referenced across resource groups, subscriptions, and tenants; the new Aspire.Hosting.Dotnet package models .NET projects by path; Radius deployment arrives in preview; and Foundry Local, Redis modules, dev tunnels, Go debugging, and other integrations gain new capabilities.

⚠️ Breaking changes

Notable changes include hosting context ServiceProvider properties being renamed to Services, PublishAsConnectionString becoming obsolete in favor of AddConnectionString, removal of aspire ps --resources and --include-hidden in favor of aspire describe, earlier proxyless endpoint port allocation, deprecation of the GitHub Models integration, removal of the dashboard AI Assistant, and opt-in rather than automatic dashboard launch from the VS Code extension.

See the full list and migration guidance in the Aspire 13.5 breaking changes.

13.4.6

What's New in Aspire 13.4.6

Patch release for Aspire 13.4 fixing polyglot AppHost code generation binding when CLI and SDK versions diverge, resource service port collision in --isolated mode, and a MongoDB.Driver dependency update.

🐛 Fixes

• 🔗 Polyglot AppHost code generation silently failed when CLI and SDK versions diverged — Aspire.TypeSystem used a floating strong-name AssemblyVersion that changed with every build. When the installed Aspire CLI was built at a different version than the AppHost's SDK, the CLR couldn't satisfy the strong-name bind and every code generator (TypeScript, Python, Java, Go, Rust) was silently dropped, surfacing as No code generator found for language: <lang>. The AssemblyVersion is now frozen at a stable constant so any compatible CLI/SDK pair on 13.4 binds successfully. Relates to #​18110 and #​17910. (#​18160, @​sebastienros)

• 🔌 Multiple AppHosts started with --isolated collided on the resource service port — Both instances tried to bind to the same fixed port from ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL, causing an "address already in use" error on the second instance. DashboardServiceHost now binds to port 0 on loopback when RandomizePorts is true (set by --isolated), letting the OS assign a unique port per instance. (#​18341, @​JamesNK)

• 🍃 MongoDB.Driver updated to 3.9.0 — Removes a wrongly pinned SharpCompress transitive dependency and uses the corrected Snappier transitive. Fixes #​17981. (#​18279, @​Falco20019)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.4.6 (#​18343)

13.4.5

What's New in Aspire 13.4.5

Patch release for Aspire 13.4 clearing a transitive MessagePack security advisory, tightening CLI validation for Playwright configuration, and adding coding-agent detection to CLI telemetry.

🐛 Fixes

• 🛡️ Bumped StreamJsonRpc to 2.25.29 to clear the MessagePack GHSA-hv8m-jj95-wg3x (CVE-2026-48109) NU1903 advisory — The transitive MessagePack 2.5.192 dependency pulled in via StreamJsonRpc 2.22.23 fell within the advisory's vulnerable LZ4 decompression range. Aspire does not use MessagePackFormatter or LZ4 — all StreamJsonRpc calls use SystemTextJsonFormatter over local Unix sockets — so the vulnerability was not reachable in practice. The bump clears the NU1903 warning for consumers of the Aspire.Hosting package. (#​18204, @​mitchdenny)
• 🎭 playwrightCliVersion values that are not valid SemVer 2.0 now fail fast with a clear diagnostic — Previously an invalid override (range expression, dist-tag like latest, or a v-prefixed string) would surface as a generic npm resolution failure. The value is now validated with strict SemVer parsing at startup; an error naming the configuration key and the offending value is emitted immediately. (#​18205, @​mitchdenny)
• 🤖 CLI telemetry now detects and reports the calling coding agent — When the Aspire CLI is invoked from inside a known coding agent environment (GitHub Copilot CLI, VS Code Copilot agent, etc.) the agent name is included in the main CLI telemetry event. GitHub Copilot CLI is specifically identified as copilot-cli. (#​18240, @​damianedwards)

🏷️ Housekeeping

• 📄 Refreshed the @​microsoft/aspire-cli npm package README to be TypeScript-only — updated examples to the current ts-starter template (apphost.mts / aspire.mjs), added a backing-services snippet showing aspire add for PostgreSQL and Redis, and documented aspire dashboard run as a standalone dashboard option. (#​18221, @​adamint)

13.4.4

What's New in Aspire 13.4.4

Patch release for Aspire 13.4 with improved DCP connection reliability during request execution and consistent ExcludeFromMcp() filtering across all CLI MCP tools.

🐛 Fixes

• 🔌 DCP requests could fail permanently when the connection dropped mid-request — If the underlying DCP channel closed while a request was in flight, the error was surfaced directly instead of being retried. Reconnection is now attempted as part of the DCP request retry path so transient disconnections recover automatically without surfacing errors. (#​18096, @​karolz-ms)
• 🔍 Resources marked with ExcludeFromMcp() were not consistently filtered from CLI MCP tools — Resources with the resource.excludeFromMcp property were not excluded uniformly from all CLI MCP tool results. list_resources, list_console_logs, execute_resource_command, list_structured_logs, list_traces, and list_trace_structured_logs all now honor the exclusion, preventing excluded resources and their telemetry from appearing in agent context. (#​18150, @​JamesNK)

🏷️ Housekeeping

• 📦 Improved npm CLI package metadata and hardened npm publish validation in the release pipeline. (#​18093, @​adamratzman)

13.4.3

What's New in Aspire 13.4.3

Patch release for Aspire 13.4 with a fix for persistent container endpoint allocation regressions introduced in 13.4.

🐛 Fixes

• 🔌 Persistent container endpoints had incorrect default behavior — Persistent containers were defaulting to proxyless endpoint behavior instead of the proxied behavior used by normal containers. This caused integrations that depend on endpoint allocation before resource startup (such as the KeyVault emulator) to fail. Persistent containers now default to proxied endpoints matching normal container behavior; opt out with isProxied: false or WithEndpointProxySupport(false). Proxyless container endpoints with only a targetPort specified now also resolve immediately to that port instead of waiting for delayed allocation. (#​17960, @​danegsta)

🏷️ Housekeeping

• 🛠️ Unblocked WinGet manifest publishing on locked-down 1ES agents and updated manifest tags (#​17958)

What's New in Aspire 13.4.2

Patch release for Aspire 13.4 with a fix for Redis persistent container deadlock on startup when using TLS.

🐛 Fixes

• 🔴 Redis with WithLifetime(ContainerLifetime.Persistent) could deadlock on startup — Redis TLS startup arguments used the public/allocated host ports instead of the internal target ports. When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable. The TLS and non-TLS startup arguments now bind to target ports, matching what Redis expects internally. Fixes #​17822. (#​17827, backported via #​17850, @​danegsta)

13.4.1

What's New in Aspire 13.4.1

Patch release for Aspire 13.4 with fixes for explicit-start resource lifecycle callbacks, Redis persistent container startup, proxyless endpoint allocation, and a duplicated profiles block in the empty C# AppHost template.

🐛 Fixes

• ⏱️ Explicit-start resources triggered lifecycle callbacks too early — Session-scoped resources marked with WithExplicitStart() were having their execution configuration callbacks (environment variables, arguments, certificates) evaluated at AppHost startup instead of at manual start. This meant user-interaction callbacks such as WithEnvironment(ctx => PromptForValueAsync(...)) were called before the user triggered the resource. DCP registration is now deferred until the user manually starts the resource; persistent explicit-start resources still register immediately but patch the existing DCP record to Start = true rather than deleting and recreating it. Fixes #​17813. (#​17825, backported via #​17826, @​danegsta)
• 🔴 Redis with WithLifetime(ContainerLifetime.Persistent) could deadlock on startup — Redis TLS startup arguments used the public/allocated host ports instead of the internal target ports. When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable. The TLS and non-TLS startup arguments now bind to target ports, matching what Redis expects internally. Fixes #​17822. (#​17827, backported via #​17850, @​danegsta)
• 🔌 Proxyless container endpoint could hang when resolved before container creation — Referencing a proxyless container endpoint in an environment variable callback (before the container port spec was finalized) could deadlock. An on-demand allocation path now commits the target port as the fallback host port in that case; once BuildContainerPorts runs, normal DCP dynamic port assignment takes over for any later resolution. (#​17851, backported via #​17859, @​danegsta)
• 📄 Empty C# AppHost template emitted duplicate profiles block — aspire new aspire-empty on 13.4 produced an aspire.config.json with a profiles block that duplicated the content already present in apphost.run.json, causing redundant launch configuration. The embedded template now contains only the required appHost.path binding; profile configuration lives exclusively in apphost.run.json. Fixes #​17660. (#​17781, backported via #​17820, @​mitchdenny)

🏷️ Housekeeping

• 📦 Added Aspire CLI npm package to the release pipeline so the npm distribution is published as part of stable releases. (#​17297, backported via #​17766, @​adamint)

13.4.0

Aspire 13.4.0

Aspire 13.4 brings major improvements to Foundry hosted agents, the Aspire skills system, CLI reliability, and TypeScript AppHost stability — with cross-compute-environment deployment now working end-to-end and TypeScript AppHost support — Aspire's polyglot story — reaching general availability (GA).

Highlights

• 🎉 TypeScript AppHost is now GA — First introduced as a preview in an earlier version of Aspire, the TypeScript AppHost — Aspire's polyglot story — has reached the quality bar for general availability and is now officially supported for production use alongside C#. As part of GA, the experimental markers on the Azure TypeScript AppHost (ATS) APIs have been removed and the ATS surface area is stable for 13.4.
• 🤖 Foundry hosted agents — Protocol selection (responses / invocations) is now configurable from both C# and TypeScript AppHosts. Cross-compute-environment deployments (e.g., a Foundry hosted agent + an AKS consumer) now wire up correctly: endpoint resolution and the required Azure AI User RBAC role assignment on the Foundry account are generated automatically — no manual az role assignment create steps needed.
• 🛠️ Aspire skills catalog from bundle — aspire agent init now drives its installable skill catalog from the bundle manifest, surfacing all six bundled skills (previously only three were visible). An embedded snapshot means the full catalog is available even in airgapped / disconnected environments.
• 🔧 CLI reliability — Multiple CLI fixes: implicit-channel discovery restored, aspire stop no longer falsely reports failure on Unix, aspire ps no longer includes raw resource data (use aspire describe for detailed state), aspire new prefers the current CLI template version, friendly error for aspire do --list-steps without a step argument, and improved --search option description with documentation link.
• ⌨️ TypeScript AppHost — Fixed a deadlock that occurred when lazy options callbacks invoked async methods; dev-localhost resource service URLs are now accepted for local development without extra configuration.
• 📊 Dashboard — Summary log formatting improved for readability, dotnet watch dashboard auto-launch signal restored, and dynamic-port handling fixed for DistributedApplicationTestingBuilder.
• ☸️ Kubernetes — The Helm CLI minimum version (≥ 4.2.0) is now validated before a Kubernetes deploy, giving a clear error instead of a cryptic failure.
• ⚠️ Aspire.Hosting.Blazor ships as preview in 13.4 — A packaging issue with the Blazor gateway scripts means the package is intentionally marked preview for this release. Full stable support is targeted for 13.5.

⚠️ Notable changes

• aspire ps no longer includes raw resource data in its output. Use aspire describe <resource> to inspect detailed resource state.
• Foundry hosted agent builder API shape updated — see #​17545 and #​17669 for the updated C# and TypeScript signatures.
• Aspire.Hosting.Blazor is preview-versioned in 13.4 (SuppressFinalPackageVersion=true). A fix for the addBlazorGateway gateway script resolution error in TypeScript AppHosts is tracked in #​17685.

What's New in Aspire 13.3.5

Patch release for Aspire 13.3 with fixes for the Azure provisioning location prompt and an Aspire CLI named-pipe timeout on Linux with .NET SDK 10.0.300.

🐛 Fixes

• 📍 Azure provisioning location prompt not populated — Selecting an existing resource group during aspire publish now correctly populates dependent server-controlled fields (such as Location). Previously, server-provided values for disabled inputs were discarded, leaving those fields blank. (#​17278, backported via #​17291)
• 🔧 Aspire CLI named-pipe timeout on Linux with .NET SDK 10.0.300 — The Aspire CLI was forcing DOTNET_CLI_USE_MSBUILD_SERVER=1 for all dotnet run/dotnet build invocations. On Linux with SDK 10.0.300 this caused a named-pipe timeout that prevented aspire run from building the AppHost. The forced override has been removed so the SDK chooses MSBuild server behavior. Fixes #​16849. (#​17313, backported via #​17314)

What's New in Aspire 13.3.4

Patch release for Aspire 13.3 with a fix for the Aspire skill description exceeding agent host limits.

🐛 Fixes

• 📝 Aspire skill description too long for agent hosts — The SKILL.md generated by aspire agent init included a frontmatter description that exceeded the 1024-character limit enforced by agent hosts such as Codex and Copilot CLI, causing the Aspire skill to fail to load. The bundled skill description has been shortened to stay within the limit. (#​17183, backported via #​17188)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.3.4 (#​17215)

13.3.3

What's New in Aspire 13.3.3

Patch release for Aspire 13.3 with fixes for debug log level leaking into user resources, Keycloak HTTPS endpoint token invalidation, and endpoint materialization in HostResourceWithEndpoints.

🐛 Fixes

• 🔇 Debug log level leaking into user resources — Logging__LogLevel__Default=Debug set by the app host was being inherited by all user resources, silently changing their logging verbosity. The app host now uses ASPIRE_APPHOST_LOGLEVEL instead, which is scoped to Aspire processes only. (#​17071, backported via #​17078)
• 🔑 Keycloak HTTPS primary endpoint — Fixed a regression where Keycloak tokens became invalid after an app host restart because the HTTPS endpoint port was dynamic. When developer certificates are enabled, Keycloak's primary endpoint is now upgraded to HTTPS directly, and the endpoint name is set to http to enable standard http+https:// service discovery URLs. (#​17058, backported via #​17063)
• 🔌 Endpoint materialization in HostResourceWithEndpoints — Endpoints configured via HostResourceWithEndpoints are now correctly materialized, ensuring endpoint resolution and service discovery work as expected. (#​17091, backported via #​17092)

🏷️ Housekeeping

• ⬆️ Bumped DCP (Microsoft.DeveloperControlPlane) from 0.23.5 → 0.23.6 — includes fixes for Kubernetes OpenAPI generator types that caused [SHOULD NOT HAPPEN] failed to update managedFields errors. (#​17070)
• 🚀 Bumped branding to 13.3.3 (#​17088)

13.3.2

What's New in Aspire 13.3.2

Patch release for Aspire 13.3 with a fix for container tunnel startup when tunnel-dependent containers use WaitFor().

🐛 Fixes

• 🚇 Fix WaitFor() for tunnel-dependent containers — The container tunnel implementation that shipped in Aspire 13.3 deadlocked at startup when tunnel-using containers waited on other resources, because resource waits blocked ResourceStarting before the tunnel initialization could complete. Container and tunnel startup have been refactored to cooperate correctly, and additional tunnel-dependent containers can now be started at any point during the application lifecycle. Also improves error reporting for container tunnel failures. (#​16988, backported via #​16993)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.3.2 (#​17053)

13.3.1

Aspire 13.3.1

What's New in Aspire 13.3.1

Patch release for Aspire 13.3 with a regression fix for aspire run and a DCP bump.

🐛 Fixes

• 🏃 aspire run compute environment validation — Skip compute environment validation in run mode so customers no longer hit Resource '<name>' is configured to publish as an Azure Container App, but there are no 'AzureContainerAppEnvironmentResource' resources. Ensure you have added one by calling 'AddAzureContainerAppEnvironment'. errors during local runs. The check is now only performed in publish mode, matching pre-13.3 behavior. (#​16945, backported via #​16952)

🏷️ Housekeeping

• ⬆️ Bumped DCP (Microsoft.DeveloperControlPlane) from 0.23.4 → 0.23.5 (#​16944)
• 🌐 Updated localization resources (#​16602)
• 🚀 Bumped branding to 13.3.1 (#​16951)

13.3.0

Aspire 13.3.0

Aspire 13.3 is here! 🚀 This release is packed with new ways to deploy, debug, and build distributed apps — including aspire destroy, browser telemetry in the dashboard, Kubernetes deployment, first-class JavaScript publishing, and major TypeScript AppHost parity
improvements.

Highlights

• 🧹 Clean teardown — New aspire destroy tears down Azure, Kubernetes, and Docker Compose deployments, and pipeline summaries make deploy/publish/destroy runs easier to follow.
• 🔍 Frontend telemetry — Aspire.Hosting.Browsers captures browser console logs, network requests, and screenshots right in the Aspire dashboard.
• ☸️ Kubernetes deploy preview — aspire deploy can now generate Helm-based Kubernetes deployments, with first-class Ingress and Gateway API routing.
• 🟨 JavaScript publishing — New PublishAs* methods support static sites, Node servers, npm-script apps, Next.js, Vite, Bun, Yarn, and pnpm.
• 🌐 TypeScript AppHost parity — Unified withEnvironment, Docker Compose hooks, endpoint expressions, Azure Container Apps domains, and more close the gap with C# AppHosts.
• 🛠️ CLI upgrades — Run the standalone dashboard with aspire dashboard run, install the CLI as a NativeAOT dotnet tool, and search API docs from the terminal.
• ☁️ Azure goodness — New Azure Front Door, Network Security Perimeter, AKS, private endpoint, and Foundry Prompt Agent support.
• 🐳 Better containers — The Aspire container tunnel is now enabled by default for consistent host connectivity across Docker Desktop, Docker Engine, and Podman.

⚠️ Breaking changes

Notable breaking changes include --log-level becoming --pipeline-log-level, the dashboard MCP server being replaced by aspire agent init, dotnet new aspire-py-starter moving to aspire new aspire-py-starter, and several API shape updates across AKS,
Foundry, JavaScript diagnostics, and TypeScript AppHost helpers.

13.5.3

What's New in Aspire 13.5.3

Patch release for Aspire 13.5 that fixes Dashboard Graph view crashes for resources with multi-path icons and restores missing public URLs for DevTunnel resources.

🐛 Fixes

• 📊 Dashboard Graph view could crash for Azure Blob resources — Resources such as those created with AddBlobs use icons containing multiple SVG paths, which caused an XML parsing exception and broke the dashboard circuit. The graph now combines multi-path icons correctly. Regression introduced in 13.5. Fixes #​19489. (#​19585, backport of #​19579, @​sebastienros)

• 🌐 DevTunnel public URLs were missing from the Dashboard and MCP snapshots — DevTunnel port resources could report Running and Healthy while showing no public URLs. Proxyless port allocation is now limited to compute and container resources, allowing DevTunnels to publish their actual public endpoints. Regression introduced in 13.5. Fixes #​19496. (#​19625, backport of #​19590, @​karolz-ms, @​danegsta)

13.5.2

What's New in Aspire 13.5.2

Patch release for Aspire 13.5 that removes an unused native helper binary from the Windows CLI archives so 13.5 servicing releases stay publishable to WinGet.

🐛 Fixes

• 🪟 Windows CLI archives shipped an unused ~4.9 MB hex1bpty.exe — The Windows CLI archives (aspire-cli-win-{x64,arm64}-*.zip) bundled Hex1b's out-of-process PTY host, which Aspire never executes (DCP owns every pseudo-terminal Aspire surfaces). Besides the wasted download, the extra unexplained executable stalled the WinGet publish, since every binary in the archive goes through executable and malware validation. A build-only MSBuild target now drops the file from the CLI publish output; Unix native assets are unaffected. Regression new in 13.5.

13.5.1

What's New in Aspire 13.5.1

Patch release for Aspire 13.5 fixing a TypeScript/Java polyglot AppHost compatibility regression when running the 13.5 SDK under an older (13.4.x) CLI, plus a DCP update and release-pipeline housekeeping.

🐛 Fixes

• 🍎 Polyglot AppHosts could crash on startup on macOS — On macOS, polyglot (TypeScript/Python/Java/Go/Rust) AppHosts could crash during startup due to an interaction between how DCP's Go runtime forks detached processes and how .NET Native AOT installs its signal handlers. Updated DCP (Developer Control Plane) to 0.25.13 to resolve the crash. ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp microsoft/aspire#19528))

• 🔗 Polyglot AppHosts on the 13.5 SDK crashed under an older CLI with MissingMethodException — A TypeScript or Java AppHost built with the 13.5 SDK failed to start when launched by an older (13.4.x) CLI, because the newer codegen called Aspire.TypeSystem members that don't exist in the CLI's older contract. Code generation now probes for these additive capabilities before using them, so older CLIs skip only the unsupported feature and startup succeeds. Regression introduced in 13.5 by #​19365. Fixes #​19503. ([#​19524]([release/13.5] Preserve TypeSystem compatibility with older CLIs microsoft/aspire#19524), backport of #​19506, @​adamint)

🏷️ Housekeeping

• 📦 Updated DCP (Developer Control Plane) to 0.25.13 ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp microsoft/aspire#19528))

• 🔧 Restored WinGet publication using .NET 9 wingetcreate ([#​19509]([release/13.5] fix(release): Restore WinGet publication with .NET 9 wingetcreate microsoft/aspire#19509))

• 🧹 Removed the pipeline-scoped Publish-Build-Assets group from the release pipeline ([#​19523]([release/13.5] Remove pipeline-scoped Publish-Build-Assets group microsoft/aspire#19523), [#​19163](Remove Publish-Build-Assets variable group from release/13.5 microsoft/aspire#19163))

13.5.0

Aspire 13.5.0

Aspire 13.5 is a developer-experience release focused on a richer, more interactive AppHost, closer C# and TypeScript parity, sharper tooling, more flexible deployment modeling, and a broad set of runtime-stability improvements.

Highlights

• 💬 Richer AppHost interactions — The Interaction Service now works across C# and TypeScript AppHosts with stable prompts and dynamic inputs, file uploads, progress dialogs, notifications, and user-defined resource command arguments that surface as dashboard controls and CLI options.
• 🖥️ Interactive terminal sessions — The experimental WithTerminal() API lets resources host REPLs, shells, TUIs, and other interactive programs directly in the dashboard, with an opt-in aspire terminal CLI command for attaching from your shell.
• 🌐 TypeScript AppHost is generally available — Polyglot AppHosts no longer require the ASPIREATS001 experimental diagnostic and gain custom health checks, container file copying, HTTPS developer certificates, faster startup, and several reliability fixes that further close the gap with C#.
• 🛠️ CLI installation and reliability — The Aspire CLI is available through npm and Nix alongside Homebrew, WinGet, mise, and NuGet. New C# AppHosts enable the CLI bundle by default, while aspire stop --force, aspire update --migrate, aspire doctor, docs search, signal handling, and stale-socket cleanup all improve day-to-day workflows.
• 🎨 Refreshed dashboard — The dashboard adopts official Aspire branding and a new accessible design-token system, with timestamp and exact numeric telemetry filters, console-log text search, clearer reconnect and health-check experiences, and correct telemetry streaming while filters are active.
• 💻 Rebranded VS Code extension — The extension is now named Aspire and adds an in-editor dashboard, Bun and MAUI debugging, resource commands in the tree view, discovered AppHosts, improved parameter handling, and more efficient workspace discovery.
• ☸️ More expressive deployments — Kubernetes and AKS gain first-class persistent volumes, Azure Container Apps adds deterministic unique resource naming, Azure environments support delegated subnets, and Docker Compose can publish Blazor gateways and configure shared memory.
• ☁️ Expanded hosting integrations — Azure resources can be referenced across resource groups, subscriptions, and tenants; the new Aspire.Hosting.Dotnet package models .NET projects by path; Radius deployment arrives in preview; and Foundry Local, Redis modules, dev tunnels, Go debugging, and other integrations gain new capabilities.

⚠️ Breaking changes

Notable changes include hosting context ServiceProvider properties being renamed to Services, PublishAsConnectionString becoming obsolete in favor of AddConnectionString, removal of aspire ps --resources and --include-hidden in favor of aspire describe, earlier proxyless endpoint port allocation, deprecation of the GitHub Models integration, removal of the dashboard AI Assistant, and opt-in rather than automatic dashboard launch from the VS Code extension.

13.4.6

What's New in Aspire 13.4.6

Patch release for Aspire 13.4 fixing polyglot AppHost code generation binding when CLI and SDK versions diverge, resource service port collision in --isolated mode, and a MongoDB.Driver dependency update.

🐛 Fixes

• 🔗 Polyglot AppHost code generation silently failed when CLI and SDK versions diverged — Aspire.TypeSystem used a floating strong-name AssemblyVersion that changed with every build. When the installed Aspire CLI was built at a different version than the AppHost's SDK, the CLR couldn't satisfy the strong-name bind and every code generator (TypeScript, Python, Java, Go, Rust) was silently dropped, surfacing as No code generator found for language: <lang>. The AssemblyVersion is now frozen at a stable constant so any compatible CLI/SDK pair on 13.4 binds successfully. Relates to #​18110 and #​17910. (#​18160, @​sebastienros)

• 🔌 Multiple AppHosts started with --isolated collided on the resource service port — Both instances tried to bind to the same fixed port from ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL, causing an "address already in use" error on the second instance. DashboardServiceHost now binds to port 0 on loopback when RandomizePorts is true (set by --isolated), letting the OS assign a unique port per instance. (#​18341, @​JamesNK)

• 🍃 MongoDB.Driver updated to 3.9.0 — Removes a wrongly pinned SharpCompress transitive dependency and uses the corrected Snappier transitive. Fixes #​17981. (#​18279, @​Falco20019)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.4.6 (#​18343)

13.4.5

What's New in Aspire 13.4.5

Patch release for Aspire 13.4 clearing a transitive MessagePack security advisory, tightening CLI validation for Playwright configuration, and adding coding-agent detection to CLI telemetry.

🐛 Fixes

• 🛡️ Bumped StreamJsonRpc to 2.25.29 to clear the MessagePack GHSA-hv8m-jj95-wg3x (CVE-2026-48109) NU1903 advisory — The transitive MessagePack 2.5.192 dependency pulled in via StreamJsonRpc 2.22.23 fell within the advisory's vulnerable LZ4 decompression range. Aspire does not use MessagePackFormatter or LZ4 — all StreamJsonRpc calls use SystemTextJsonFormatter over local Unix sockets — so the vulnerability was not reachable in practice. The bump clears the NU1903 warning for consumers of the Aspire.Hosting package. (#​18204, @​mitchdenny)
• 🎭 playwrightCliVersion values that are not valid SemVer 2.0 now fail fast with a clear diagnostic — Previously an invalid override (range expression, dist-tag like latest, or a v-prefixed string) would surface as a generic npm resolution failure. The value is now validated with strict SemVer parsing at startup; an error naming the configuration key and the offending value is emitted immediately. (#​18205, @​mitchdenny)
• 🤖 CLI telemetry now detects and reports the calling coding agent — When the Aspire CLI is invoked from inside a known coding agent environment (GitHub Copilot CLI, VS Code Copilot agent, etc.) the agent name is included in the main CLI telemetry event. GitHub Copilot CLI is specifically identified as copilot-cli. (#​18240, @​damianedwards)

🏷️ Housekeeping

• 📄 Refreshed the @​microsoft/aspire-cli npm package README to be TypeScript-only — updated examples to the current ts-starter template (apphost.mts / aspire.mjs), added a backing-services snippet showing aspire add for PostgreSQL and Redis, and documented aspire dashboard run as a standalone dashboard option.
