ADO.NET is a set of computer software components that can be used by programmers to access data and data services. It is a part of the base class library that is included with the Microsoft .NET Framework. It is commonly used by programmers to access and modify data stored in relational database systems, though it can also be used to access data in non-relational sources. ADO.NET is sometimes considered an evolution of ActiveX Data Objects (ADO) technology, but was changed so extensively that it can be conceived of as an entirely new product.
It makes sense to me as ADO.NET, specifically DataSets and DataTables, have good code-generation support, are stored as XML, and make it very easy to get data presented very quickly. ADO.NET objects have XML Web services support and with partial classes, DataSets can be extended and regenerated (and that's a good thing).
