title: Exception not caught in Task.Run wrapped method
body: <p>New to async await integration in C# 5.  I'm working with some basic Task based methods to explore async await and the TPL.  In this example below I'm calling a web service with a timeout of 5 seconds.  If the timeout expires it should throw an exception so I can return false from the method.  However, the timeout never occurs, or maybe it does but the Task never returns.</p>
  
  <pre><code>public static Task&lt;bool&gt; IsConnectedAsync()
  {
      return Task.Run(() =&gt;
      {
          try
          {
              using (WSAppService.AppService svc = new NCSoftware.Common.WSAppService.AppService(GetServiceUrl(WebService.app)){Timeout = 5000})
              {
                  return svc.PingB();
              }
          }
          catch (Exception ex)
          {
              Logger.LogException(ex.Message, ex, "IsConnectedAsync");
          }    
          return false;
      });
  }
  </code></pre>
  
  <p>If you could please help with how to properly handle this so that if the timeout occurs or even better, an exception occurs, the Task does return.</p>
