-## Validating Setup
-
-Before moving on, let's validate that the reference to our game library was setup correctly and can be referenced within the game project.  To do this, we're going to add a simple class we can use to measure the frames per second (FPS) that our game is running at. First, create a new class file named *FramesPerSecondCounter.cs* in the *MonoGameLibrary* project.  Then add the following to the class file:
-
-```cs
-using System;
-using Microsoft.Xna.Framework;
-
-namespace MonoGameLibrary;
-
-public class FramesPerSecondCounter
-{
-    // Represents one second of time
-    private static readonly TimeSpan s_oneSecond = TimeSpan.FromSeconds(1);
-
-    // Keeps count of the total number of frames that have elapsed.
-    private int _counter;
-
-    // Tracks the current amount of time that has elapsed.
-    private TimeSpan _timer;
-
-    /// <summary>
-    /// Gets the calculated total of frames per second.
-    /// </summary>
-    public int FramesPerSecond { get; private set; }
-
-    /// <summary>
-    /// Creates a new FramesPerSecondCounter instance.
-    /// </summary>
-    public FramesPerSecondCounter()
-    {
-        _counter = 0;
-        _timer = TimeSpan.Zero;
-    }
-
-    /// <summary>
-    /// Updates this FramesPerSecondCounter.  
-    /// </summary>
-    /// <remarks>
-    /// Should only be called once during the main game update.
-    /// </remarks>
-    /// <param name="gameTime">Snapshot of the timing values provided by the MonoGame framework.</param>
-    public void Update(GameTime gameTime)
-    {
-        // Increment by the total amount of time elapsed between frames.
-        _timer += gameTime.ElapsedGameTime;
-
-        // If more than a single second has elapsed, set the frames per second
-        // to the total counted, reset the counter, and decrement the timer
-        // by one second
-        if (_timer > s_oneSecond)
-        {
-            FramesPerSecond = _counter;
-            _counter = 0;
-            _timer -= s_oneSecond;
-        }
-    }
-
-    /// <summary>
-    /// Updates the FramesPerSecondCounter during the draw cycle of the game.
-    /// </summary>
-    /// <remarks>
-    /// Should only be called once during the main game draw cycle
-    /// </remarks>
-    public void DrawUpdate()
-    {
-        // We increment the counter only during draw since each draw completes
-        // a frame cycle.
-        _counter++;
-    }
-}
-```
-
-Now that we have a class within the game library project to reference, let's ensure it can be referenced.  Perform the following
-
-1. Open the *Game1.cs* file in the *MonoGameSnake* project.  At the top of the file where the `using` statements are located, locate the `using Microsoft.Xna.Framework.Input` statement and add the following on a new line below it:
-
-    ```cs
-    using MonoGameLibrary;
-    ```
-
-2. Locate the `private SpriteBatch _spriteBatch;` member declaration and add the following on a new line below it:
-
-    ```cs
-    private FramesPerSecondCounter _fpsCounter = new FramesPerSecondCounter();
-    ```
-
-3. Locate the `Update` method and add the following:
-
-    ```cs
-    _fpsCounter.Update(gameTime);
-    ```
-
-4. Finally, locate the `Draw` method and add the following:
-
-    ```cs
-    _fpsCounter.DrawUpdate();
-    Window.Title = "{_fpsCounter.FramesPerSecond}FPS";
-    ```
-
-If you run the game now, you should see the title of the game update to show the game name and the total frames per second it is running at.

-
-> [!TIP]
-> If you receive an error that the type or namespace for `MonoGameLibrary` or `FramesPerSecondCounter` could not be found, this means the project reference was not setup correctly.  Revisit the [Adding a Reference to the Class Library](#adding-a-reference-to-the-class-library) section above and ensure that the reference is added properly.
