<p class=MsoNormal style='margin-bottom:12.0pt'>I have a small hosting class
that works on a WinForms app. But it gives an InvalidProgramException when
called from a NUnit test.<br>
<br>
The test project is within the IronPython solution and I've referenced
IronPython, IronPython.Modules and Microsoft.Scripting.<br>
<br>
I'd like to know if other people were able to test hosting using NUnit.<br>
<br>
Thanks.<br>
