SQL Server Data Types in the .NET Framework

The SqlTypes library is part of the base class library of the Microsoft .NET Framework. It is designed to provide data types with the same semantics and precision as those found in the SQL Server database. This topic describes the new semantics to .NET Framework programmers, and introduces the types implemented in the System.Data.SqlTypes namespace that is included in the System.Data library.
