Thank you for contacting us! Any issue or feedback from you is quite important to us. We will do our best to fully respond to your issue as soon as possible. Sometimes additional investigations may be needed, we will usually get back to you within 2 days by adding comments to this issue. Please stay tuned.

Note: Restarting Visual Studio Code and trying again did not resolve the issue.

Thanks @pierceboggan for the feedback!

From your attached log (the dotnet-sdk-3.1.411-osx-arm64.tar.gz part), we are guessing that your are using an Mac with M1 chip.
Could you please confirm that?

Our toolkit depends on .NET 5 or .NET SDK 3.1. However neither .NET 5 nor .NET SDK 3.1 supports M1 Mac yet (see this github issue).

Our current design is the users will follow the "learn more" link to install .NET manually in case they work on M1, so this is the expected behavior. But we think your feedback is great and we will update our document to clarify the issue of .NET SDK on M1 Mac explicitly.

If you have any other questions, please let us know.

I am blocked on this too with my m1 MacBook. Is there a way to install .NET 6.1 which has support for m1 chips and use with the msteams vscode extension?
