ADO.NET 2.0 includes enhanced type support for the DataSet using System.Data.SqlTypes. System.Data.SqlTypes are designed to provide data types with the same semantics and precision as the data types in a SQL Server database. Each data type in System.Data.SqlTypes has an equivalent data type in SQL Server 2005, with the same underlying data representation.
