Add WinUI control to control library

[sam-wheat]

I am following these instructions to create a control library.

Choose the template flavor based on your library's flavor: UWP or WinUI. If your project uses the Uno.UI NuGet package, it's UWP otherwise WinUI 3 if it uses Uno.WinUI.

I'm not really sure what "your project" means since dependencies are per-platform. My intent is to use WinUI 3 and when I look at Dependencies/netstandard2.0/packages I see a reference to Uno.WinUI 4.6.19 so I presume I'm good there.

Problem is when I "Right-click on the project library, then Add, New Item" per the doc I only see UWP templates. The words "Choose the template flavor..." make me think I should see WinUI as well as UWP (??).

When I choose Custom Contro (Uno Platform UWP) a control is added to the project however references to Windows.UI.Xaml.Controls, Windows.UI.Xaml.Data, etc. are not found the project does not build.

How can I create a WinUI control in the project?

I am targeting .net 7 per my question here.
Using VS 17.4.1

We're currently adjust those templates so that they fit better with the WinUI/WinAppSDK scenario. In the meantime, you can create a UWP one, then rename anything Windows.UI.Xaml to Microsoft.UI.Xaml in both the .xaml and .xaml.cs files.
