After the first code transfer, adding a user using a register is not performed:
Cannot insert NULL value in the column "Discriminator", table "aspnet-BSF2013-20130918101120.dbo.AspNetUsers"; column does not allow null.
The generated user code is the default code generated by the project template (project Vs2013, MVC with EF5)
Before the successful migration, the registration code worked, so I assume that the membership was changed by EF.
