very nice could you also please upgrade the bundled MSBuild to 16.9 as well? It seems to work with .NET 6.0 currently, but it's still 16.8

ah you are right. We used to ship those as separate zips, but I forgot we stopped doing that

I think when this is merged, it's a good time to trigger a new release, it's been a while

I want to follow up this afternoon with a PR to update Roslyn to either our 3.9.0 package or possible 3.10 preview1.
