I'm trying to make a project using Entity Framework, but I've run into a problem.
When the model is created (I call Database.EnsureDeleted() first) it throws:
Unhandled Exception: System.InvalidOperationException: The entity type 'CustomAttributeData' requires a primary key to be defined.

Which I find rather odd because I have nothing to do with CustomAttribute.
I've tried removing all CustomAttributes from my classes as well, but that didn't make a difference.
Maybe it's because i'm serializing an abstract class rather than an implementation?
I hope someone can point me in the right direction.
