1. Derive a class from Game.
2. After creating the GraphicsDeviceManager, set its PreferredBackBufferWidth and PreferredBackBufferHeight to the desired screen width and height.
3. Set IsFullScreen to true.

//Game1.cs

public class Game1 : Microsoft.Xna.Framework.Game
{
    GraphicsDeviceManager graphics;
    ContentManager content;


    public Game1()
    {
        graphics = new GraphicsDeviceManager( this );
        content = new ContentManager( Services );

        graphics.PreferredBackBufferWidth = 800;
        graphics.PreferredBackBufferHeight = 600;
        graphics.PreferMultiSampling = false;
        graphics.IsFullScreen = true;
    }


    protected override void Initialize()
    {
        // TODO: Add your initialization logic here.

        base.Initialize();
    }


    protected override void LoadGraphicsContent( bool loadAllContent )
    {
        if (loadAllContent)
        {
            // TODO: Load any ResourceManagementMode.Automatic content.
        }

        // TODO: Load any ResourceManagementMode.Manual content.
    }


    protected override void UnloadGraphicsContent( bool unloadAllContent )
    {
        if (unloadAllContent == true)
        {
            content.Unload();
        }
    }


    protected override void Update( GameTime gameTime )
    {
        // Allows the default game to exit on Xbox 360 and Windows.
        if (GamePad.GetState( PlayerIndex.One ).Buttons.Back == ButtonState.Pressed)
            this.Exit();

        // TODO: Add your update logic here.

        base.Update( gameTime );
    }


    protected override void Draw( GameTime gameTime )
    {
        graphics.GraphicsDevice.Clear( Color.CornflowerBlue );

        // TODO: Add your drawing code here.

        base.Draw( gameTime );
    }
