title: Remove borders winforms and WindowState Maximized without fullscreen
body: <p>I have the following trouble and i don't find a solution.</p>
  
  <p>I want to implement a Winform without top bar and if is possible, without borders. I tried several things without success, the following would do the trick perfectly :</p>
  
  <pre><code>        this.Text = string.Empty;
          this.ControlBox = false;
          this.FormBorderStyle = FormBorderStyle.SizableToolWindow;
  </code></pre>
  
  <p>producing the following result :</p>

  <p>The little problem is when me or the user trigger the maximize state , because will make the form enter in a FULLSCREEN mode ! and i don't know how to prevent this:</p>
