When I do this, I get the following error:
`There is already an object named 'Company' in the database. --->
System.Data.SqlClient.SqlException: There is already an object named '
Company' in the database.`
If not using IAutoMappingOverride what do you recommend?
Create an IList in Person? Like `IList<Company> Companies`
