Someone recently asked about how to load test WCF - apart from the usual things like LoadRunner , VSTS Test Load Agent , etc a couple of other interesting options came up. One is WCF Load Test and the other JMeter. WCF Load Test generates a unit test taking in data from a a trace file along with the relevant WCF proxy or interface.

I must admit, JMeter would not have been one of the things that would have come to mind to me in this context, but technically there is nothing stopping from you using it as you can stress and load test any http request.
