Upgraded to .net 6 Preview 7 and workload commands are failing

See original GitHub issue

Describe the bug

I upgraded to VS2022 Preview 3 and attempted to follow the instructions for removing the old aot workload and received this failure:

C:\WINDOWS\system32>dotnet workload uninstall microsoft-net-sdk-blazorwebassembly-aot

Removing workload installation record for microsoft-net-sdk-blazorwebassembly-aot...
Garbage collecting for SDK feature bands ...
Workload uninstallation failed: The JSON value could not be converted to Microsoft.NET.Sdk.WorkloadManifestReader.WorkloadPackId. Path: $.Id | LineNumber: 0 | BytePositionInLine: 45.
uninstall
  Uninstall a workload.

Usage:
  dotnet [options] workload uninstall [<WORKLOAD_ID>...]

Arguments:
  <WORKLOAD_ID>  The NuGet Package Id of the workload to install.

Options:
  -?, -h, --help  Show help and usage information

I think this occurred because after a failed VS2022 installation yesterday I completely removed VS2022 and the entire preview6 & preview7 runtimes. So presumably the installed aot workload did not exist. So I believe that this is just a bad error message.

However, when I attempted to install the wasm-tools workload I got

C:\WINDOWS\system32>dotnet workload install wasm-tools

So it looks like there is a missing nuget package

I found a solution which is working for me.

Steps

  1. Delete C:\Program Files\dotnet\metadata\workloads folder
  2. Go to CMD (Admin)
  3. run “dotnet workload install maui”

Seeing what’s probably a similar issue upgrading from Preview 6 to Preview 7

> dotnet new console -o testenv
