Rollout

• Include the Roslyn-based GenAPI as a secondary backend for SBRP generator. Add switch option to turn-on/off it.
• Create a Maestro subscription between the dotnet/sdk and the dotnet/source-build-reference-packages and between the dotnet/arcade and the dotnet/source-build-reference-packages in order to automate the flow of the cci-based and the roslyn-based GenAPI into the dotnet/source-build-reference-packages
  Create a Maestro subscription between dotnet/sdk and dotnet\source-build-reference-packages #12462
• Run tests to confirm that SBRP generator produces correct SBRPs:
  • Oleksandr ran a SBRP generator with the Roslyn backend to generate 40+ sbrp reference packages
  • Generate the microsoft.codeanalysis.* and microsoft.build.* reference package
    • Generate reference assembly of microsoft.build, with Roslyn-based GenAPI #11350
    • Generate reference assembly of microsoft.build, with Roslyn-based GenAPI #11350
• Write a handover message and communicate with the Runtime team about what we implemented, how we tested, known issue.
• Solve the The Source Build Reference Package generator uses assembly references from net6.0 target framework to resolve references for all TFMs. source-build#3237
  Solving this issue 'd allow us to pass correct assembly references and improve the quality of generated reference assemblies.
  We made an agreement with the Runtime and the A&D teams to not invest into the cci-based GenAPI backend and improve just the SBRP generator with the Roslyn-based backend.
• Merge the documentation Update readme file. Describe supported backend options. source-build-reference-packages#523
• Write a wooo-hooo email.

Documentation

https://github.com/dotnet/source-build/blob/main/Documentation/eliminating-pre-builts.md

• The documentation must cover the usage of both backends: the cci-based and the roslyn-based GenAPI.
• The documentation must answer the questions:
  • How to search for a log file and navigate it?
  • How to analyze and solve reference resolution errors of the SBRP generator?
  • How to build each reference package separately.
  • Where to report bugs roslyn api, or GenAPI, or SBRP generator.
