Generic Dialog Manager example.

[Shadowblitz16]

Topics to cover

It would be nice if there was an example on how to show a window or dialog from a generic view model.

	public static void ShowWindow<T>(this T context, string title, uint width, uint height) where T : BaseViewModel
	{
		var topLevel = DialogManager.GetTopLevelForContext(context);
		if (topLevel != null && !Windows.TryGetValue(typeof(T), out var window))
		{
			window = new Window();
			window.Content = ViewLocator.Get(context);
			window.Title   = title;
			window.Width   = width;
			window.Height  = height;

		}
		window.Show();
	}

             x:DataType="vm:LayerViewModel"
             services:DialogManager.Register={Binding}>

Ideas for a sample

• Showing window
• Hiding Window
• Toggling window
• Async Dialog
• Mvvm view model based
• Similar setup to dialog example by registering it to a user control.
