VS2013 Debugger + Entity Framework: “runtime has refused to evaluate the expression”, crashes

Question

I\'m experiencing a lot of problems with Entity Framework 6.0.1 in the VS2013 Ultimate debugger when debugging into unit tests against code that\'s hitting a live SQL Server

Answer 1

I am having a similar problem and although I'm yet to understand why, turning Options -> Debugging -> General -> Use Managed Compatibility Mode - On, allowed me to continue debugging as normal.

I found this option via this blog post.
