I've just started using XNA Studio Express and Programming in C# so my knowledge is kinda minimal. So I've started with the tutorials 2D Cannon game that MS provide, but I'm stack on loading a background
because although it compiles perfectly when I run it, it says that it can't find the file. But i followed everything to the letter
        protected override void LoadContent()
        {
            spriteBatch = new SpriteBatch(graphics.GraphicsDevice);

            backgroundTexture =
                Content.Load<Texture2D>("Sprites\\background");   <--------Here

            //Create a Rectangle that represents the full
            //drawable area of the game screen.
            viewportRect = new Rectangle(0, 0,
                graphics.GraphicsDevice.Viewport.Width,
                graphics.GraphicsDevice.Viewport.Height);

            base.LoadContent();
        }

Could someone help me pls : )

In your project there is a Content folder/section. Ensure your background texture is placed in a folder called Sprites (under the Content folder).

If you are using Xna 3.0 then the properties of the background file should be: (Xna 2.0 is slightly different e.g. BuildAction might be Content instead of Compile).

Asset Name: background
BuildAction: Compile
Importer: Texture - XNA Framework
Processor: Texture - XNA Framework

when you build (or rebuild) check the build output window to see something like:

Building Sprites\background.jpg -> C:\...\Bin\Content\Sprites\background.xnb

then when the build is done, check the Content\Sprites folder in your bin folder for a file called background.xnb

Thank you for your help, I got it to work : )
