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…

A service contract describes the operations supported by a service,the message exchange pattern they use,and the format of each message. The service contract is also the main driver for generating a service description. A valid WCF service implements…

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…

In Chapter 1,you were introduced to fundamental WCF concepts,      在章节1中,学习了wcf中的基础概念including how to create and consume a service,           包括如何创建以及调用服务how to host a service and expose endpoints where it can be reached by clients,    如何托管服务,使得客户端可以…

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…

How messages reach a service endpoint is a matter of protocols and hosting. IIS can host services over HTTP protocol,the Windows Activation Service (WAS) can support others such as TCP and named pipes,and self-hosting can support many protocols and i…

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…

So far in this chapter,I have shown you different ways to create services,how to expose a service endpoint and metadata exchange endpoint,how to generate client proxies,how to work with metadata,and how to configure service behaviors. In this section…

由于在实际开发中,Silverlight需要调用WebService完成数据的获取,由于之前我们一直采用古老的ASMX方式,生成的代理类不仅难以维护,而且自身没有提供APM模式的调用方式,导致在Sinverlight中实现线程同步,非常的困难.所以这里我采用了WCF Restful Service来完成. 这里我们需要新建一个WCF Rest Service Application项目: 然后在项目中,我们删掉原有的示例文件,添加一个QDService.cs类,并设为Partial模式,以便于实…
