The dotnet-affected tool cannot run on .NET 6.

You can invoke the tool using the following command: dotnet-affected

Having some CI troubles. It looks like the script is sucessfully installing the .NET 6 SDK:
https://github.com/leonardochaia/dotnet-affected/runs/4166725509?check_suite_focus=true#step:3:23

However, the dotnet restore step does not seem to find the SDK:

Simply use https://github.com/actions/setup-dotnet for installation dotnet. it should work.

Hi @omer-za .
This project has a script to install the proper versions required when developing. We use that as well in CI so that we don't have any differences between CI and local development.

That being said, this should be fixed by now, but I'm not sure if a new release has been issued from NuGet, the SDK or whoever needs to fix this :P

For tracking purposes see microsoft/MSBuildSdks#309 and NuGet/Home#11376
