The FCL includes a set of classes that access data sources and manage complex data sets. Known as ADO.NET, these classes are the managed replacement for ADO under Win32. ADO.NET supports both connected and disconnected operations, multiple data providers (including nonrelational data sources), and serialization to and from XML.
