If you’ve been writing WCF services for a while, you know that this technology gives you superior flexibility for providing and consuming services. There are many permutations with which you can configure your services but this flexibility is not the only thing that makes WCF an incredible technology. You can also hook into the WCF runtime to provide your own customizations that get called upon when your services do. In this session, I’ll demonstrate this with a couple of techniques for achieving call monitoring and call authorization. You’ll learn how to write parameter inspectors, operation behaviors, and service behaviors; and how to install and reuse them easily.
