Is WCF Redundant?

It’s funny, when alternative technologies comes out that do a similar thing to a previous technology, people are very quick to pronounce the previous technology as dead. I was talking to someone the other week at a different company who said that their architects wanted to use WebAPI because WCF wasn’t relevant any more. This made me think, WHAT!!, REALLY!!, SURELY NOT!!

WCF is Dead. All Hail Web API
WCF is Dead. All Hail Web API

In the rest of this article I want to briefly cover what WCF and WebAPI are, talk a bit about the differences, and then suggest the reasons why you may use either. This isn’t an exhaustive discussion, but the point is that you can have various technologies doing similar things, without either one of them being redundant. I have spent the last 7 years of my career being involved in service architectures built using WCF and I am certainly not thinking I need to replace any of those systems just yet.
