In this WCF tutorial we introduce the primary reasons for moving from other technologies to WCF as well as how to get started using WCF. Prior to .Net 3.0 it was not an easy matter to select a particular technology for communicating between systems due to the number of technologies available from Microsoft. For example, users could have used Web Service to communicate between a Java based application and a .Net application; WSE users could have take advantage of some of the WS-* message protocols; MSMQ has the ability to queue messages which helps to communicate between intermittently connected solutions; Enterprise services (the successor of COM+) helps to build distributed application easily; .Net Remoting is a fast way to move messages between two .NET applications. All the above mentioned technologies have their pros and cons. Using WCF now we can take the advantage of all the above distributed technologies in a unified manner and WCF is the successor to all these message distribution technologies.
