Just wanted to let everyone know that I just uploaded a patch that has an MSBuild task to make it easier to run PartCover if you are using MSBuild for automation.
It handles automatically registering/deregistering the CorDriver.dll from the install directory so that you can include it in your vcs system and not need it installed on every machine.
I've only tried it using NUnit at this point, but it seems to work ok.
Would love to see that included in a future version. :)
