FSharp.DependencyManager.Nuget ignoring sources

[kevmal]

If a nuget source has name with a space in it then it's skipped. Looks like the regex assumes no spaces:

fsharp/src/FSharp.DependencyManager.Nuget/FSharp.DependencyManager.Utilities.fs

Lines 312 to 342 in 1492e70

	// 2. dotnet-tools [Enabled]

Thank you for this Kevin. In my case it was affecting interactive, see: dotnet/interactive#3289

Just to reiterate: This issue appears to be the root cause of this issue

dotnet/interactive#3289

Likely broken in this PR: #14769

Seems not to like package sources with spaces in the name

[KevinRansom]

Okay, I understand now.

The issue occurs when the sources are specified in a Nuget.config file alongside the script.

For example:
A script that says:

#r "nuget:FSharp.Compiler.Service, 43.8.300-dev"

Alongside a Nuget.config file containing:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!-- Only specify feed for Arcade SDK (see https://github.com/Microsoft/msbuild/issues/2982) -->
  <packageSources>
    <clear />
    <add key="MySourceDirectory" value="C:\\temp\\repro\\my source  directory" />
  </packageSources>
</configuration>

Will not find files the nuget package in: "C:\temp\repro\my source directory".

This is certainly a bug, and I will fix it. In the mean time this is equivalent and will work.
Update the script to include the source using the #i directive

#i "nuget:C:\\temp\\repro\\my source  directory"
#r "nuget:FSharp.Compiler.Service, 43.8.300-dev"
