Description

On the DesktopGL platform, it's possible to access the game window during UnloadContent. This makes it possible to save the window size and position for example. The window is only disposed during the Platform.Dispose:

MonoGame/MonoGame.Framework/Platform/SDL/SDLGamePlatform.cs

Lines 329 to 339 in a91dcc7

	protected override void Dispose(bool disposing)
	{
	if (_view != null)
	{
	_view.Dispose();
	_view = null;
	Joystick.CloseDevices();
	Sdl.Quit();
	}

On the WindowsDX platform, the Windows is disposed earlier in Platform.Exit:

MonoGame/MonoGame.Framework/Platform/Windows/WinFormsGamePlatform.cs

Lines 71 to 77 in a91dcc7

	public override void Exit()
	{
	if (_window != null)
	_window.Dispose();
	_window = null;
	Window = null;
	}
