dotnet workload update fails with a `JsonReaderException` #18339

I installed the blazor-aot workload using .NET 6 preview 4. After installing the preview 5, I ran dotnet workload update. This command fails with a JsonReaderException

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

rajeshaz09 commented 3 years ago

I believe Json structure changed. from p4 to p5. I also faced same issue. Delete C:\Program Files\dotnet\metadata\workloads folder and install once again.

meziantou commented 3 years ago

You may be right. I've deleted the folder, run install and update => no error :)

sfoslund commented 3 years ago

@rajeshaz09 is correct, this is a known compat issue between prev 4 and 5. Closing as won't fix, since this won't be an issue with GA.
