EF Data migrations won't detect changes when adding new migration

Question

I am using Entity Framework 5.0 Data migrations along with code first. When i add a new field to my model and execute the following command in the package manager console.

Answer 1

It seems that i managed to solve the problem by moving the models and the context class to another project.

I still have no idea why this happened, and this solution is really no solution at all :(
