title: Form1.cs [Design] disappeared
body: <p>I think I goofed up and my WinForms designer is missing now. I noticed this in my <code>Form1.Designer.cs</code> file:</p>
  
  <pre><code>    /// &lt;summary&gt;
      /// Required method for Designer support - do not modify
      /// the contents of this method with the code editor.
      /// &lt;/summary&gt;
  </code></pre>
  
  <p>I deleted one line from this file because I accidentally added an extra button. I deleted it from the GUI designer but the code still remained. So I just deleted it.</p>
  
  <p>My application compiles and runs correctly. But after poking around in Visual Studio for 20 minutes now &amp; Googling I can't seem to get <code>Form1.cs [Design]</code> file to come back.</p>
  
  <p>Basically this file (pic taken from Google)</p>

  <p>The <code>Form1.cs [Design]</code> displayed some sort of error but I closed the tab. Now I can't seem to even get the tab back to see the problem.</p>
