A MbUnit fixture runs in it's own thread. By default, it uses the same AppartmentState as the main thread. If you want to force using another value, you can use the AppartmentState field in the constructor:

// A fixture running in STA
[TestFixture(ApartmentState = ApartmentState.STA)]
public class MyFixture
{
   [Test]
   public void DoingCOM()
   {
      ....
   }
}

Make sure to add "using System.Threading" at the top of you file. Also, small typo, only on "p" in Apartment. Posted by marcstober at Sep 13, 2005 20:03
