How to resize window using XNA

Question

I know this question has been asked many times before. However, all solutions I have found after over an hour of googling are essentially the same thing. Everyone says that

Answer 1

The GraphicsDevice.Viewport width and height by default on my computer is 800x480, try setting a size above that that will be noticeable - like 1024x768.

graphics.PreferredBackBufferHeight = 768;
graphics.PreferredBackBufferWidth = 1024;
graphics.ApplyChanges();

The above code in Initialize was sufficient to expand the window for me.
