Bazuzi.AzureFunctionAnalyzers

Roslyn analyzers for common Azure Functions patterns.

Rules

Id	Title
AZURE_FUNCTIONS_0001	Function class name should match the function name
AZURE_FUNCTIONS_0002	Prefer ILogger<T> over ILogger
AZURE_FUNCTIONS_0003	Prefer injecting ILogger<T> over FunctionContext.GetLogger()
AZURE_FUNCTIONS_0004	Class should contain only one Azure Function
AZURE_FUNCTIONS_0005	Route constraint is incompatible with the parameter type

Examples

class UserGetter
{
    [{|#0:Function("GetUsers")|}] // warning: Class name 'UserGetter' does not match function name 'GetUsers', expected 'GetUsersFunction'
    public void Run()
    {
        //...
    }
}

^{snippet source | anchor}

[Function("GetUsers")]
public void Run(FunctionContext context)
{
    var logger = {|#0:context.GetLogger("GetUsersFunction")|};  // warning: 'logger' should be typed 'ILogger<GetUsersFunction>' instead of 'ILogger'
    //...

^{snippet source | anchor}

class GetUsersFunction
{
    [Function("GetUsers")]
    public void Run(FunctionContext context)
    {
        var logger = {|#0:context.GetLogger<GetUsersFunction>()|};  // warning: Use constructor-injected ILogger<GetUsersFunction> instead of calling 'GetLogger'
        //...
    }
