'WTG.Analyzers.Framework.Test.CodeFixerTest.AnalyzerMock': A project containing analyzers or source generators should specify the property '<EnforceExtendedAnalyzerRules>true</EnforceExtendedAnalyzerRules>'

This compiler extension should not be implemented in an assembly with target framework '.NET Framework 4.7.2'. References to other target frameworks will cause the compiler to behave unpredictably. (https://github.com/dotnet/roslyn-analyzers/blob/main/docs/rules/RS1041.md)

This compiler extension should not be implemented in an assembly containing a reference to Microsoft.CodeAnalysis.Workspaces. The Microsoft.CodeAnalysis.Workspaces assembly is not provided during command line compilation scenarios, so references to it could cause the compiler extension to behave unpredictably.
