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…

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…

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…

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…

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…

WCF中的Contracts WCF通过Contract来说明服务和操作,一般包含五种类型的Contract:ServiceContract,OperationContract,FaultContract,DataContract,MessageContract. 1.ServiceContract ServiceContract向外部暴漏了可以提供的服务接口,它可以包含服务名称.命名空间等服务器端的配置信息. 1: [ServiceContract] 2: interface IMyContr…

In machine learning, is more data always better than better algorithms? No. There are times when more data helps, there are times when it doesn't. Probably one of the most famous quotes defending the power of data is that of Google's Research Directo…
