ColNameMap.TryGetValue(colName, out colMapping);

Mapper doesn't work when column and POCO property are in different case (For example: item_id and Item_ID)

[VitaliyMF]

That's correct, in case if column and property are different:

• use [Column("item_id")] data annotation attr to specify column name (like for EF)
• or use DbDataAdapter.Select(..).SetMapper(customMapHandler).ToList<Model>() to specify custom mapping logic
