The problem is that you've defined the connectionStrings section twice (as you can see in the Detailed Error Information:

Config section 'connectionStrings' already defined.

Delete the first one.

UPDATE:

Check the following: Entity Framework Code First Migrations failing on Wrong Provider (3.5 instead of 4.0)

And don't forget to add the required references: System.Data.Linq and System.Data.SqlServerCe.dll version 4.0.0.0.
