Hi.
I don't know if it's a proper way to do this, but it seems to work.
In your Game.cs file in Main() function replace game.Run(); with following:
| System.Windows.Forms.Control control = System.Windows.Forms.Form.FromHandle(game.Window.Handle); |
| System.Windows.Forms.Form form = control.FindForm(); |
| form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; |
| game.Run(); |
Of course you must add reference to System.Windows.Forms in your project.
