Publish of a hosted Blazor WASM project fails

[MarkStega]

Describe the bug

When I use VS2022 to publish my hosted Blazor WASM application (consisting of the .Net server, several 'standard' dll's, a Blazor webassembly dll, and a Razor class library) the publish succeeds. After moving the content of the publish into my IIS application I can launch the application and it works.

When I try to use the CLI to publish it fails with:

Hello, thanks for contacting us. Could you please double check if C:\Solutions\OHI\Optimiser\Optimiser.2021.Blazor\Optimiser.2021.Blazor.csproj exists on disk?

Hello @TanayParikh , I just created a Blazor WebAssembly project using Visual Studio 2022.
After creating the project, I cannot even run it for the first time without changes. The error is the same.

Error Could not find %(ResolvedRuntimePack.PackageDirectory)= Test1 C:\Program Files\dotnet\packs\Microsoft.NET.Runtime.WebAssembly.Sdk\6.0.0-rc.2.21480.5\Sdk\WasmApp.targets

This is pointing to an error in WasmApp.targets, line 161, where the very first error condition hits on the following xml

<Target Name="_InitializeCommonProperties">
   <Error Condition="'$(MicrosoftNetCoreAppRuntimePackDir)' == '' and ('%(ResolvedRuntimePack.PackageDirectory)' == '' or !Exists(%(ResolvedRuntimePack.PackageDirectory)))"
          Text="Could not find %25(ResolvedRuntimePack.PackageDirectory)=%(ResolvedRuntimePack.PackageDirectory)" />
   <Error Condition="'$(IntermediateOutputPath)' == ''" Text="%24(IntermediateOutputPath) property needs to be set" />

   <PropertyGroup>

   </PropertyGroup>

   <MakeDir Directories="$(_WasmIntermediateOutputPath)" />
 </Target>

To answer your question, yes in my environment I can see the csproj file.

Hope this is useful!

[MarkStega]

@TanayParikh
Yes the csproj is there and the dll gets created as expected when the solution is built.

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.
