Back Buffer Property In Windows Phone

Back Buffer is the surface area on which XNA constructs the graphics which we want to display in the Draw method.

800*40 is the by default back buffer size.

Here we set the width and height of the Back Buffer:-

graphics.PreferredBackBufferWidth=100;

graphics.PreferredBackBufferHeight=200;

There are another property called PreferredBackBufferFormat, which is used to set the format of the back buffer.
