A Blazor WebAssembly app crashes at runtime due to a missing DLL for the Shared project. This happens after I makes any change to the app, e.g. in Index.razor in the Client project. The Shared project remains unchanged.

The exact exception is:

FileNotFoundException: Could not load file or assembly [AppName].Shared.dll

If I clean and rebuild the solution, it runs again, until I make another change.

If I uninstall the Telerik Blazor Visual Studio extension, the error goes away. Alternatively, another possible workaround is to reduce the number of parallel builds in Visual Studio to 1.

The Upgrade (Project) Wizard crashes on the screen where it askes whether to use a backup.

The "Show me more" link gives this:

The wizard encountered an error while trying to handle user event.

System.NullReferenceException: Object reference not set to an instance of an object.

I cannot continue to the next page. I want to upgrade the existing 3.5 to 3.6
