When calling a stored procedure from DbContext I get the following exception:

System.Reflection.TargetParameterCountException: Parameter count mismatch.

We are calling a method via reflection. Method expects one argument, but we pass two. It is likely that overload that took two parameters was removed during dead code cleanup (since we call it via reflection it's easy to miss).
