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.

Did you by any chance have installed a previous SDK preview and installed workloads for it? While we added update, it won't work with preview 4 and before last I checked and may not work 6->7. It'll work better once we're out of previews and the workload names have all stabilized to their final names.

I have the same issue when upgade my project from 2.2 to .net core 6, When I tried to build source code with visual studio 2022 it shown error as below, Is that the issue fixed on lastest version? (7.0.0 RC 1)
