Languages indicate the different types of applications that can be built in .NET Framework. If you are new to .NET Framework, you may not be familiar with some of the applications listed here:

• ADO.NET: In an ADO.NET application, we write programs to access data from sources such as SQL Server, OLE DB, and XML sources.
