I'm digging with a very strange problem... I've a bunch of tests that fails using R# integrated test runenr, but are ok using NUnit GUI, Gallio Icarus Runner and TestDriven.Net runner!
I've checked my code with the debugger, and looks like my objects are in an invalid status using R# runner and are ok with other runners: as example a collection that is empty in NUnit is not empty using R# (and in my code actually i create a new empty collection!).
Anyone experiencing problem like this?
