title: Custom Build Activity Not Running
body: <p>I have a custom build activity, but it's not executing. I've put it in try-catch block which catches <b>Sysytem.Exception</b> in my build template, and first line of overriden execute method is throwing <b>Sysytem.Exception</b>. On the log I see only line with the name of my custom activity! Any guesses?</p>
  
  <pre><code>     protected override void Execute(CodeActivityContext context)
       {
          throw new System.Exception("This is hello messasge");
          ...
       }
  </code></pre>
