Database in use error with Entity Framework 4 Code First

Question

I have an MVC3 and EF 4 Code First application, which is configured to change the DB when the model changes, by setting the DB Initializer to a DropCreateDatabaseIfMod

Answer 1

I found in EF 6 this fails with an ALTER DATABASE statement not allowed within multi-statement transaction error.

The solution was to use the new transaction behavior overload like this:

context.Database.ExecuteSqlCommand(TransactionalBehavior.DoNotEnsureTransaction, "ALTER DATABASE [" + context.Database.Connection.Database + "] SET SINGLE_USER WITH ROLLBACK IMMEDIATE");
