Hi,

I am trying to make integration test of my application. One of the UI
control is the webbrowser, that has it's own thread for refreshing. It
means the main application is a STA, but the WebBrowser control is not
STA,
that causes the exception below. Are anyways to ignor multithreaded
controls? Thanks.
I.e. NUnit does not throw such exception.

Regards,
Tricky.

The error body:

TestCase 'Test_SubmitCaseDropWorkItem.TestSubmitCaseDropWorkItem'
failed: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot
be instantiated because the current thread is not in a single-threaded
apartment.

Add [TestFixture(ApartmentState=ApartmentState.STA)] to your test.

This is now the default in MbUnit v3.

Jeff.

It says 'ApartmentState is not declared'. I added ApartmentState =
System.Threading.ApartmentState.STA.
It looks that there is no such attribute in the version 2.4. What do
you think? Thanks.

I think I might have mispelled it...
It's in there for sure.
