Release Notes

These release notes are a comprehensive list of changes from 1.22.0 to 1.23.0-pre.3.

Extensibility Analyzers

• We have created xUnit3003 to flag classes which extend FactAttribute (directly or indirectly) which do not provide a constructor that collects and passes along source location information (file name and line number). This is used to provide source information to Microsoft Testing Platform runners, like Test Explorer and dotnet test, to link tests to their source code.

  This analyzer is only applicable to projects which are linked against xUnit.net v3 version 3.0.0 or later.
