title: Visual Studio 2012 testing with csla and entity framework
body: <p>In VS2010 my MSTest test run just fine.</p>
  
  <p>When running in VS2012 I am getting an error. The test sets the Csla.ApplicationContext.User with a Custom Business Principal. When the EntityFramework is asked to provide a new ObjectContext I receive a SerializationException saying that my Custom Business Principal type cannot be found.</p>
  
  <p>All the tests that use the EntityFramework fail when running through VS2012's test runner or Resharper7's test runner. I have tried NCrunch's test runner and they all pass.</p>
  
  <p>How can I resolve this issue?</p>
