I have updated the PR per the public swagger, and run msbuild build.proj (Anyway, don't see any change by run msbuild).
Would you please help to review and merge the PR asap?
Thanks!

@blueww When are you planning to release a stable version? Ideally you should have started preview versioning from 8.8.0-preview and landed on 9.0.0 stable version. Do let us know when you are planning to move to version 10 so we can provide a better idea.
Not blocking on this
