| Related DevelopMentor Courses | MORE | | WCF Instances and Threading I have just found myself answering essentially the same question 4 times on the MSDN WCF Forum about how instances, threading and throttling interact in WCF. WCF has 3 built in instancing models: PerCall, PerSession and Single. In practical terms it means that for Session supporting bindings: NetTcpBinding, WSHttpBinding, NetNamedPipeBinding, etc, every proxy gets an instance on in the service. By default WCF assumes you do not understand multithreading. Unless you turn on ASP.NET Compatibility, WCF calls are processed on IO threads in the system threadpool. DevelopMentor Courses - Friday, February 4, 2011 Roll Your Own REST-ful WCF Router Recently I’ve been tasked with building a WCF routing service and faced the choice of whether to go with the built-in router that ships with WCF 4.0 , or to build one from scratch. However, as the MSDN documentation for the WCF Router states, “ The Routing Service does not currently support routing of WCF REST services. In fact, using the BasicHttpBinding with AspNetCompatibility enabled on the built-in WCF router results in a somewhat cryptic error : “Shouldn’t allocate SessionChannels if session-less and impersonating.”.

The goal of WCF was to provide a unified API for communication and to be able to provide a common level of service irrespective of the underlying transport. To understand the structure of WCF and why it looks the way it does useful starting point are the four tenets of service orientation. There are three core concepts at play whenever you use WCF: messages, channels and encoders. Message is a first class construct in WCF and are modeled on SOAP messages.

DevelopMentor Courses - Sunday, April 7, 2013 WCF SOAP and REST Multi-Project Visual Studio Templates What I like about this sort of project template is that it produces a much more realistic WCF solution with entities spit off into a separate project that is referenced from both the service and client projects. ve been doing quite a bit more WCF work lately and found myself creating the same kind of WCF SOAP projects over and over again. So I dusted off my blog post on building multi-project Visual Studio templates and set off to build a WCF SOAP Multi-Project Template , which I uploaded the Visual Studio Extensions Gallery.

| The Best from DevelopMentor | MORE | - WCF Duplex Messaging
I am one of the moderators of the MSDN WCF Forum. However, the first three of these are supported natively in WCF and are known as One-way, request/response and duplex. Duplex Contracts in WCF. In WCF this idea is modelled by the contract. This gives the service access to a proxy to call back to the client. WSHttpBinding is the default for the built in WCF projects but it does not support duplex messaging. Irrespective if which of the standard bindings you are using, duplex assumes a constant relationship between proxy and service. flowcharts!” .NET Meanderings - Tuesday, June 9, 2009 - WCF Instances and Threading

DevelopMentor Courses - Friday, February 4, 2011 - Using Silverlight to Access WIF secured WCF Services
Another technology that comes up very often is Silverlight – and especially the “story” of Silverlight and WCF/WIF. Those of you with WCF background will say: “that’s what the federation bindings in WCF are for”. Afterwards you can attach the header to outgoing calls: var factory = new ChannelFactory ( "client" ); var proxy = factory.CreateChannel(); using ( var scope = new OperationContextScope (proxy as IContextChannel )). {. In WCF you can work around that problem by adding the ValidateMustUnderstand behavior to the client stack. Passive.

DevelopMentor Courses - Sunday, April 7, 2013 - WF4&WCF and message correlation
In the previous blog posts, here , here and here , I demonstrated how to use WCF from WF4. One of the ugly parts of Windows Workflow Foundation 3 was the message correlation part when you used WCF to send multiple messages to the same workflow. This guid was the workflow instance ID but having to use that on the client means the client had to be very aware of the server technology used, something that goes against the principals of WCF. No longer do we need to use the “context” bindings but the standard WCF bindings will do just fine. Much better! OperationContract].

cache.AddTokenToCache( "myRP" , args.Result); }; client.IssueAsync(rst); Using a Token to authenticate with a WCF Relying Party. This allows calling a WCF service like this: private void CallService(). {. var factory = new ChannelFactory ( "myRP" ); var proxy = factory.CreateChannel(); var channel = proxy as IContextChannel ; channel.SendWithIssuedToken(_cache.GetTokenFromCache( "myRP" ), () => {. proxy.BeginGetClaims(result => ShowClaims(proxy, result), null ); }); }. thought I give this another shot with the new SL/WIF integration. www.leastprivilege.com - Sunday, March 21, 2010 %>
