What are ADO.NET and WCF? Is ADO.NET deprecated with WCF or part of WCF?
ADO.NET and WCF serve for different purposes. ADO.NET makes it easy to connect to a database, while WCF allows you to communicate over a pipe (thereby potentially replacing web services).
See here for the ADO.NET tutorial and here for one on WCF.
A complete single thing.

WCF is the basis for communication between systems. Many WCF applications will use ADO to work with the final repository.
These are independent technologies that deal with various problems.
WCF is a technology for creating services. The main difference from a simple web service is that a wcf service can work with various protocols (http, tcp, netpipes)
