What are some easy and simple unit testing frameworks to use with Visual Studio 2010 Express vb.net?
Are there any good tutorials geared towards this?
It may not be true anymore, but previous versions of VS Express weren't able to install any plugins. This meant that you couldn't use the integrated test-runners, but that's really not that big of a deal.
Worst case is that you use VS to write your tests and compile both, then manually run your tests using their testrunner external to VS. The most common unit-testing platform for .NET is nUnit which includes a standalone test runner.
