Minimal repo to reproduce dotnet/aspnetcore#35345

Steps to reproduce the issue

• Build the RazorClassLibrary project (in VS, right-click -> Build)
• Run the following command in the MyBlazorApp folder: dotnet publish

This error pops-up:

C:\Program Files\dotnet\sdk\6.0.100-rc.1.21463.6\Microsoft.Common.CurrentVersion.targets(5109,5): error MSB3030: Could not copy the file "C:\path\to\repo\StaticWebAssetsBug\RazorClassLibrary\obj\Debug\net5.0\staticwebassets\RazorClassLibrary.StaticWebAssets.xml" because it was not found. [C:\path\to\repo\StaticWebAssetsBug\MyBlazorApp\MyBlazorApp.csproj]

Running dotnet publish a second time works fine.

How to create this repo?

• Create a templated Blazor App
• Add a templated Razor Component Library
• Refernce the RCL from the app and use a component from it.
