title: This VS example project shows blank forms in the designer, why?
body: <p>The newer <a href="https://code.msdn.microsoft.com/Simple-Multi-User-TCPIP-1ff0da41" rel="nofollow noreferrer">Simple Multi-User TCP/IP Client &amp; Server using TAP</a> example by the genius Reed Kimble, when opened in VS 2015 Community, shows blank forms for both client and server:</p>

  <p>What I mean is, the form designer shows empty forms for both, however the control creation code does exist in the .vb files, leading to a working assembly, without the ability to redesign the form. (In any graphical way, anyhow.)</p>

  <p>Googled this "issue" for more than several hours. Apparently this is fairly common. I found out that it is often due to a broken .vbproj file:</p>
  
  <pre><code>&lt;Compile Include="Form1.vb"&gt;
    &lt;SubType&gt;Form&lt;/SubType&gt; 
  &lt;/Compile&gt;
  &lt;Compile Include="Form1.Designer.vb"&gt;
    &lt;DependentUpon&gt;Form1.vb&lt;/DependentUpon&gt;  '&lt;-- this is often missing!
  &lt;/Compile&gt;
  </code></pre>
  
  <p>I checked all .vbproj files and these all seem correct. There are no errors at project load or build. Does anyone have a clue what <em>else</em> would cause this behavior?</p>
