Simple topmost semi-transparent window using MonoGame
Add a MonoGame Windows Project, and change the base class of your game from OverlayGame.
public class Game1 : OverlayGameOverlayGame inherits from Game and it makes the window layered, transparent, top-most and unclickable.
It looks like a semi-transparent sticker on your screen, or even a HUD.
Drawing on the window looks like drawing directly on screen.
See OverlayWindow.Sample for a fullscreen window that renders MonoGame's logo.
