title: Which unit testing framework?
body: <p>I wondered which unit testing framework would be a good one to get really familiar with?  I know this might be a question of opinion, but I thought I'd ask anyways.  I know that I will need to do it someday, so I might as well learn to use it. I know that there is quite a few out there, but which one is effective for C# development?</p>
  
  <p>From <a href="https://stackoverflow.com/questions/286587/are-you-really-using-unit-tests">this</a> question I can see that unit testing is necessary, but personally I haven't used it.  So that's why I ask this question.</p>
