WPF app with BlazorWebView fails to compile the Razor components

Description

I created a WPF app with a BlazorWebView and then tried to add the code for the default Blazor template, but I get a compilation error saying that one of the namespaces is missing, even though I have components in the Shared folder:

This reproduces locally for me. There's something weird about everything in Shared in here. It's like it's somehow not in the compilation at all. Razor works just fine, as long as you don't have anything in Shared. Yet the C# compilation has the relevant AdditionalFiles with all the right paths...

Let's spent one day to understand what is the issue here first. Depending on the findings and how much time will be required to address that issue we'll then decide whether this will be supported for the initial release or not.

For time being, customers can add their components in Razor Class Libraries instead.
