Lack of Support for MsTest

It's franly quite annoying how little support there is for Visual Studio testing. What are Microsoft thinking with the multiple flavours of the product? I didn't realise that some didn't have the test tools, frankly this is scary for our TDD friends. Perhaps considering the support there is for nUnit (not least nCover - theres nothing for MsTest apart from a tool a colleague and I wrote http://sourceforge.net/projects/mstestuncovered) it would worth thinking about migrating.
