     <!-- ReactiveUI.SourceGenerators runs beside this generator in the contract tests: its attributes are referenced,
          and its generators are loaded from the package rather than run over this project. This project pins the first
          release the contract follows; the Roslyn 4.13 project runs the same tests against the current release. -->
