Question

We are working with entity framework 4.1 – code first. We need to be able to name our constraints and not have their names auto-generated by SQL Server. Is this possible?

We need: PK_Users_UserId,
Not: PK_Users_87329729C

Answer 1

Could you run some raw sql to rename them after creation? You may need to disable the EdmMetadata convention.

context.Database.ExecuteSqlCommand(
  @"DECLARE @pk sysname
    SELECT @pk = name FROM sysobjects WHERE parent_obj = object_id('users') and xtype = 'pk'
    EXEC sp_rename @pk, 'pk_users_UserId'
");
