This document summarizes an advanced WCF topics training module. It covers creating WCF services and clients in code, securing WCF services through various transports, bindings and authentication mechanisms, and using the Windows Azure Service Bus for connectivity and messaging between applications. The module includes demonstrations of creating services and clients in code, securing services, and using the Azure Service Bus.

7. WCF Service Security
• WCF Security basically boils down to
– Transport security (SSL/HTTPS)
– Message Security (Encrypting the payload)
• There are a number of ways to accomplish the above using
– Bindings
– Transports
– Authentication mechanisms
– Certificates…..
