title: SAS Enterprise guide migration from 4.3 to 5.1
body: <p>I created 9 add-ins in a project in VS 2008. And I builded project so VS created a .dll file. Using this way</p>
  
  <pre><code>Tools -&gt; Add-in -&gt; Add-in Manager -&gt; Browse -&gt; (choose .dll which I created at VS 2008)
  </code></pre>
  
  <p>when I add add-in's .dll file to SAS Enterprise Guide 4.3, it works perfectly, EG 4.1 recognizes all of add-ins in .dll. But when I add add-in's .dll file to SAS Enterprise Guide 5.1, SAS EG 5.1 shows only 8 add-ins. It doesn't recognize one of them.</p>
  
  <p>How can I solve this problem?</p>
