Hello Noemata, thank you for opening an issue with us!

@Noemata there's a weird hard dependency on a specific version of some SDKs that VS doesn't install automatically. :( We're trying to better document this here: https://github.com/windows-toolkit/WindowsCommunityToolkit/pull/3115/files

But we also need to try removing our globals.json. If you check the version of the .NET Core 3.0.x SDK you have, make sure to modify the globals.json file to match it.

Wow @michael-hawker. You were right. Thank you.

My previous dotnet --info was:

And with the installation of dotnet-sdk-3.0.101-win-x64.exe, it now reads:

I suppose the good news is that all the .Net Core SDKs play along with each other.

You're welcome to close this issue once the docs are a tad more clear on this requirement, although this is something that perhaps should come along with the VS2019 install payload as a default.

@Noemata Glad the info provided by Michael helped resolve the problem. We have a PR open in terms of doc instructions and requirements and will be merged soon.

Closing this as the Doc PR was merged.
