XAML designer/previewer

[davepruitt]

Description

We need a XAML designer/previewer, and I am not talking about "hot reload". We need something that works during design time. Using "hot reload" requires the user/programmer to run the app and then navigate to the correct screen before being able to view/change the UI.

Having a XAML designer/previewer (like what previously existed for Xamarin Forms and what has always existed for WPF) would be excellent for designing user interfaces.

Public API Changes

None.

Intended Use-Case

Any time anyone wants to design a user interface... so basically everyone who ever uses MAUI.

Having this issue marked as a duplicate and subsequently closed makes me feel like the MAUI team isn't really listening.

This isn't a duplicate of 3439. Issue 3439 is requesting a "drag-and-drop" GUI development tool, similar to What has existed for Winforms in products such as Visual Basic in the past. While that requested is related to this one, it is distinctly different.

This request is specifically asking for a XAML designer/previewer like what is available for WPF and was available for Xamarin Forms.
