IDisposable implementation - What should go in 'if (disposing)'
// Dispose(bool disposing) executes in two distinct scenarios.
// If disposing equals true, the method has been called directly
// or indirectly by a user's code. Managed and unmanaged resources
// can be disposed.
// If disposing equals false, the method has been called by the
// runtime from inside the finalizer and you should not reference
// other objects. Only unmanaged resources can be disposed.
protected virtual void Dispose(bool disposing)
{
    if (!disposed)
    {
        if (disposing)
        {
            // Free other state (managed objects).
        }

         // Free your own state (unmanaged objects).
         // Set large fields to null.
         disposed = true;
     }
 }
