dotnet workload install wasm-tools breaks build of ordinary csproj projects

[AArnott]

Describe the bug

I was building a Blazor project, and it recommended I install the wasm-tools workload so that output could be optimized. I did so.
Now all my csproj's fail to build with errors about the Aspire SDK, which I have never installed nor want to install:

Error occurred while restoring NuGet packages: Invalid restore input. Invalid target framework 'unsupported'. Input files: D:\source\repos\Nerdbank.Cryptocurrencies\src\Nerdbank.Zcash.App\Nerdbank.Zcash.App.Desktop\Nerdbank.Zcash.App.Desktop.csproj.
1>C:\Program Files\dotnet\sdk\8.0.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.props(14,3): error MSB4019: The imported project "C:\Program Files\dotnet\packs\Aspire.Hosting.Sdk\8.0.2\Sdk\AutoImport.props" was not found. Confirm that the expression in the Import declaration "C:\Program Files\dotnet\packs\Aspire.Hosting.Sdk\8.0.2\Sdk\AutoImport.props" is correct, and that the file exists on disk.

Removing wasm-tools appears to have fixed the problem. So I strongly suspect the latest version of that workload somehow assumes I installed Aspire as well.

[sjrulandch]

Thanks for the post. Just hit this issue as well...

I had to remove: wasm-tools, ios
Worse I had to uninstall via VS installer.
5 months and this is still broke.
Great way to encourage me to NOT try other features in VS. Thanks MS.

Just hit it myself. Trying to clean it up I run across a big fat error running dotnet workload clean now. Thanks MS!

@dotnet/aspnet-blazor-eng or @lewing I'm not sure who owns this... 😅

[lewing]

@radical can you take a look? the error seems to be coming from the aspire workload
