How to fix problems with entity framework migrations

1. First – backup the __MigrationHistory table in the database
2. Get rid of old migration files
3. add-migration using the usual syntax, but with nothing modified
4. Remove all of the “Create Table”, etc – the migration should look like

public partial class domorenow : DbMigration
{
public override void Up()
{

<code>    }

    public override void Down()
    {

    }
}</code>

6. from there do the update-database -script to generate a sql file
7. then just update-database -verbose
8. All Fixed
