Windows Communication Foundation(WCF) 是由微软开发的一系列支持数据通信的应用程序框架，可以翻译为Windows 通讯开发平台。整合了原有的windows通讯的 .net Remoting，WebService，Socket的机制，并融合有HTTP和FTP的相关技术。是Windows平台上开发分布式应用最佳的实践方式。 WCF 的服务可以挂载于 Console Application，Windows Application，IIS (ASP. NET) Application，Windows Service以及Windows Activation Services中，但大多都会挂在 Windows Service。 WCF 的基本概念是以契约(Contract) 来定义双方沟通的协议，合约必须要以接口的方式来体现，而实际的服务代码必须要由这些合约接口派生并实现。合约分成了四种：数据契约(Data Contract) ，订定双方沟通时的数据格式。 [DataContract]//一般接口返回的数据都会带上DataContract特性,这样方便我们控制返回的数据 public class WCFUser { //[DataMember]//不被标记DataMember特性的字段不会返回 public int Id { get; set; }

WCF并发连接数的问题

阅读更多关于 WCF并发连接数的问题

在最近的开发中，总是发现人数一多就会有用户莫名其妙的界面卡死，或者直接掉线的情况，不知道是什么原因，由于项目采用的是netTcp绑定，猜想可能是并发连接的问题。于是查了一下: 在windows7中，并发连接数默认是10 代码 < binding name ="netTcpBindConfig" closeTimeout ="00:30:00" openTimeout ="00:30:00" receiveTimeout ="00:30:00" sendTimeout ="00:30:00" transactionFlow ="false" transferMode ="Buffered" transactionProtocol ="OleTransactions" hostNameComparisonMode ="StrongWildcard" listenBacklog ="10" maxBufferPoolSize ="2147483647" maxBufferSize ="2147483647" maxConnections ="10" maxReceivedMessageSize ="2147483647" > 将项目移植到windows server2008上之后，并发连接数需要改变一下，于是变成代码 < binding name ="netTcpBindConfig"

问题 I have a WCF service which is hosted as a Windows Service. We would like to enable a mex endpoint at the same address (but with a '/mex' suffix). I have been trying to do this (unsuccessfully) using the following configuration: <system.serviceModel> <services> <service name="MyCompany.MyService" behaviorConfiguration="defaultServiceBehavior"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost"/> </baseAddresses> </host> <endpoint address="MyService" binding="netTcpBinding" contract=

Using WCF on Localhost on Azure

阅读更多关于 Using WCF on Localhost on Azure

问题 In summary How do I acces a WCF service on localhost when hosted in IIS on Azure? Azure does not bind localhost or 127.0.0.1 to my website. Details I have an ASP.Net application hosted on Azure. I have added a .svc and some workflows that I want to use via WCF. To keep matters simple, my web app simply calls the service on localhost, so I have endpoints like these in web.config; <client> <endpoint address="http://localhost:8080/Router.svc/Case" binding="basicHttpBinding" contract="NewOrbit

WCF Serialization problems with WSDL file created by Java tools

阅读更多关于 WCF Serialization problems with WSDL file created by Java tools

问题 My team is tasked with getting several in-house developed .NET client applications to connect to some new Java web services. The Java web service is a third party, vendor supplied WSDL file that our team has a limited ability to modify/control...meaning we probably have the power to request our vendor to make slight tweaks to the WSDL, but major changes would probably be either unfeasible or difficult to request. That said, we are attempting to utilize WCF/.NET 4.0 to generate the .NET proxy

问题 Given a WCF interface definition like this, is there a way to exclude a property from the ComplexObject response value? I want to exclude the ChildObjects property. I don't want to remove the DataMember attribure from the property definition as I need it to be serialized in another case.

In WCF, server hasn't accessed client's public key and client hasn't accessed server's public key - still the web-method operation is successful. Why?

阅读更多关于 In WCF, server hasn't accessed client's public key and client hasn't accessed server's public key - still the web-method operation is successful. Why?

问题 I have a WCF service on a dev server secured with X.509 server certificate ( .pfx ) [not self-signed, organization provided] using message security. On my local machine, a client app consumed it with a client certificate ( .pfx ) [not self signed] file using message security. The intended operation (web service method) worked successfully with required result. Client service call : try { ServiceClient.Service1Client obj = newServiceClient.Service1Client(); Response.Write(obj.Add(1, 1)); }
