Using the WindowsAppSdk for packaging in a single project wpf app with Blazor Hybrid doesn't compile

[EddyHaigh]

Describe the bug

If you add the WindowsAppSdk.Runtime for the packaging of a single project WPF app this works and produces an msix. However, adding Blazor Hybrid to solution seems to confuse Webview 2 and the components for Blazor Hybrid suddenly become unavailable.

Steps to reproduce the bug

1. Setup a WPF single project msix app
2. Add Blazor Hybrid (v9+)

Expected behavior

The app should build an MSIX.
