title: Difference between Unit tests project in c# and a class library with xunit
body: <p>Ok so I have been a long time xunit user, and I have always used it in a class library. Infact I didn't even realize there was an actual unit tests project type. </p>
  
  <p>So my question is...what do you get in a unit tests project you do not get in regular project types? </p>
