title: Automatic testing with WinForms and NUnit
body: <p>I'm using Cruise Control.NET and NAnt to automatically run NUnit tests on our code base.  Some tests cause Windows forms to be shown.  When these tests are run manually from VS or NUnit GUI, they work fine.  When run via the Cruise Control service, I get the following exception:</p>
  
  <pre><code>System.InvalidOperationException : Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
  </code></pre>
  
  <p>Short of excluding the test altogether or rewriting the test so the form is not shown, is there any other way I can modify the test or get NUnit to run these tests when called from a service?</p>
