Adding Uno.Extensions.Maui.WinUI.Markup automatically if they use MAUI and C# markup

[LuisAlfredo92]

What would you like to be added:

Adding Uno.Extensions.Maui.WinUI.Markup automatically automatically when you use MAUI Embedding and C# Markup

Why is this needed:

Not to have to install it manually and deal with versions that can cause problems with Uno.Extensions.Maui.WinUI, and to be there since the beginning when creating a C# Markup project like other extensions

For which Platform:

• iOS
• Android
• WebAssembly
• WebAssembly renders for Xamarin.Forms
• Windows
• Build tasks

Anything else we need to know?

I can add it myself, I'll do it

Thanks for the report and effort to make a contribution!

This is a change that needs to be made in unoplatform/uno. It's managed directly by this block:

uno/src/Uno.Sdk/targets/Uno.Implicit.Packages.ProjectSystem.targets

Lines 42 to 45 in f9a5c1f

	<ItemGroup Condition="$(UnoFeatures.Contains(';csharpmarkup;'))">
	<_UnoProjectSystemPackageReference Include="Uno.WinUI.Markup" ProjectSystem="true" />
	<_UnoProjectSystemPackageReference Include="Uno.Extensions.Markup.Generators" ProjectSystem="true" />
	</ItemGroup>

And most likely needs an additional block that checks for maui as well.
