SubSonic 3.0 and Substage

Don't know if you have the latest bits from SVN with a bug, but my version from a few days ago appears to be working fine. Here is what my DB class starts off with:

public partial class DB : IQuerySurface
{
    BatchQuery _batch = null;

    public IDataProvider DataProvider;
    public DbQueryProvider provider;

    private IDatabaseSchema _schema;
    public IDatabaseSchema Schema
    {
        get
        {
          return _schema;
        }
    }

    public DB() 
    { 
        DataProvider = ProviderFactory.GetProvider("Northwind");
        Init();

    }

    public DB(string instanceName, string connectStr)
    {
        SubSonic.DataProviders.ConnectionStringProvider.Instance.AddLocalConnectionString(
              instanceName, connectStr, "System.Data.SqlClient");

        DataProvider = ProviderFactory.GetProvider(instanceName);

        Init();

    }

... etc...

I used the advanced version of the templates.

The templates generate a new class that implement IQuerySurface, the name of which you can configure in the main .tt file (usually something like NorthwindDb). Usually all that is needed is to pass a new instance of this class to the repository:

_StaffingPositionsRepository = new SubSonicRepository<StaffingPosition>(new StaffingDB());
