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…

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…

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…

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…

SummaryThis chapter covered a lot of ground,beginning with a look at the purpose of WCF,the problems it solves and its alignment with SOA,through discussion of the fundamentals developers should know before they begin working with WCF. I also touched…

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…

Hosting Multiple Service Implementations On The Same Port With WCF Recently I have been playing around with WCF and Visual Studio 2008.  I was building a set of web services.  The project consisted of two difference service interfaces (IServiceA and…

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…

At its core,WCF is a development platform for service-oriented applications. As I mentioned earlier,WCF is part of the .NET Framework 3.0,which comprises a set of new assemblies that rely on the .NET Framework 2.0. System.ServiceModel is the assembly…

以前项目解决方案中,用http协议的asmx Web service作服务器数据访问入口,在SoapHeader中写入用户名和加盐密码进行身份认证. http asmx服务是明文传输,传输过程中数据很容易被截取.篡改.在内网使用.用户量小.安全问题不严重的情况下运行几年,没有出过大的问题. 但随着项目的发展,需要对服务器进行改造,升级成更高级的安全方式. 最先想到的是将http协议改用https,解决数据明文传输泄密以及有可能被篡改,造成服务器数据严重混乱问题. 但是,https传输存在两个问题…

示例代码下载地址:WCFDemo1Day 概述 客户端向WCF服务发出请求后,服务端会实例化一个Service对象(实现了契约接口的对象)用来处理请求,实例化Service对象以及维护其生命周期的方式在WCF中共有三种不同的类型,分别是: Per-Call Per-Session Single 程序中通过设置ServiceBehavior特性来指定,如下: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] p…

WCF ServicesWCF services are the new distributed boundary in an enterprise application—with an emphasis on SOA. In the past,you had to deliberate between Enterprise Services,.NET Remoting,or ASMX to distribute and reuse functionality,WCF provides you…

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…
