How do you manage deterministic finalization in C#?

class MyDisposableObject : IDisposable
{
   public MyDisposableObject()
   {
   }

   ~MyDisposableObject()
   {
      Dispose(false);
   }

   private bool disposed;
   private void Dispose(bool disposing)
   {
      if (!this.disposed)
      {
          if (disposing)
          {
             // Dispose of your managed resources here.
          }

          // Dispose of your unmanaged resources here.

          this.disposed = true;
       }
   }

   void IDisposable.Dispose()
   {
      Dispose(true);
      GC.SuppressFinalize(this);
   }
}

public void DoingMyThing()
{
   using (MyDisposableObject obj = new MyDisposableObject())
   {
      // Use obj here.
   }
}
