I am building an application which utilizes code first migrations in entity framework. Previously, I have been able to add migrations and update the database, however, recently I added a c# class to the application and added the migration. Now when I update the database I get the error message "Sequence contains more than one element." I cannot figure why this is happening and I need some one to help me with code so I can correct this issue and update the database.

I eat this kind of debugging for breakfast :) I will need access to the code, obviously (either access to your source control or a zip file of the project). Very quick turnaround, or no charge.
