Looks like we need to merge the #43015 code flow first to address the error message.

error NETSDK1045: The current .NET SDK does not support targeting .NET 10.0. Either target .NET 9.0 or lower, or use a version of the .NET SDK that supports .NET 10.0. Download the .NET SDK from https://aka.ms/dotnet/download

@v-wuzhai the other PR is now in so we can fix the merge conflicts and start getting this one unblocked.

ci checks passed @marcpopMSFT
dotnet/roslyn#75795 is making roslyn net5+ to roslyn version mapping dynamic, which warns during msbuild:LangVersion binding in template engine, until that target is updated. with dynamic approach, it'd be the last time that roslyn file needs an update

Should we remove the 9.0 templates (like we removed 8.0 from the 9.0 branch)?
Should we unwind 426b043?

We can do those changes in a separate PR. Still not sure why the net9.0 version is missing from the test run as it'll be needed eventually. Is that because we're using a VS image that doesn't have 9 yet maybe?

[marcpopMSFT]

Approving assuming we'll do the other changes I outlined in a separate PR.

[v-wuzhai]

@marcpopMSFT I will submit a separate PR to address the issues you mentioned.

[v-wuzhai]

@marcpopMSFT I have created an issue to track the missing net9.0 templates: #44736. We will update our test environment once the templates are available.
