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
I just wanted to add my voice to the crowd here.
I am developing a UWP app, not using the Entity Framework, and experienced a similar issue where the runtime "refused to evaluate the expression".
I was using Microsoft Visual Studio Enterprise 2015 Update 2 and the solution for me was for me to update to Update 3.
