NUnit Build Task - Specify App.config file

Hello all,

I need to specify an App.config file for my NUnit tests to run against.  I was accomplishing this using the MSBuild runner with an NUnit task, however I am trying to set up dotCover integration and it seems this requires the tests to be in a seperate NUnit build step.  There does not seem to be a place to specify a config file in the TeamCity UI.

Any thoughts?

Thanks!
