Q: check public API changes as part of the build

[tmds]

Some of the dotnet repos check for public API changes as part of the build.

I haven't tried figuring out how it works.

Is this tooling available, and can it be used for C# library projects?

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

This is accomplished via ApiCompat which is used in the runtime libraries build. @safern is working on productizing ApiCompat: dotnet/designs#177

Thanks @ViktorHofer !
