In the previous lab,you created a service and client from scratch without leveraging the tools available to WCF developers. Although this helps you to understand the raw requirements for sending messages between clients and services,in reality,develo…

You’re about to be introduced to the WCF service. This lab isn’t your typical “Hello World”—it’s “Hello Indigo”! In this lab,you will learn how to build a new WCF service and in the process learn the minimum requirements of service development and co…

A data contract describes how CLR types map to XSD schema definitions. Data contracts are the preferred way to enable serialization of complex types included in operation signatures as parameters or return values. You create a data contract by applyi…

So far I’ve talked about the standards behind it all,but in fact WCF hides most of this from the developer by providing a programming interface for designing service contracts and controlling the message format. Application messaging requirementsare…

While messaging protocols are responsible for message serialization formats,there must be a way to capture the protocols required to communicate between clients and services. In Chapter 1,you worked with WSDL documents,which describe the requirements…
