I have been on this for days.

Please help with the snapobject v.2.0 usage below.

How do i make snapobject to run the multi-table sql query defined in DwSelectAttribute on the D_Rpt_Mm_Tbills poco class


public List<D_Rpt_Mm_Tbills> Test(params object[] parameters)
{
 var test = _context.SqlModelMapper.Load<D_Rpt_Mm_Tbills>(parameters).ToList();
 return mapper;
}

D_Rpt_Mm_Tbills class
