    Using is used for namespace resolution. For example:

    using System.Data;

    lets you access the DataSet class without typing in the fully qualified name; System.Data.DataSet.

    This doesn’t however tell the compiler what assembly (DLL) the DataSet class lies in. So you need to tell it. So you refer to System.Data.dll by adding it to the references section in solution explorer.
