channelfactory

I've began to learn WCF and wish to understand its internals by creating a simple Web server using channel stacks directly. I have found a lot of theory in the web but I'd like to see a working sample code of receiving and responding an httprequest that I can test using any browser. I'm hoping for something that shows the setup of a custom binding by assembling binding elements all the way to responding the request. Got the answer in MSDN forums : static void RunService() { //Step1: Create a custom binding with just TCP. BindingElement[] bindingElements = new BindingElement[2]; bindingElements

I'm building a series of WCF Services that are going to be used by more than one application. Because of that I'm trying to define a common library to access WCF services. Knowing that each service request made by different users should use a different Channel I'm thinking in cache the Channel per-request ( HttpContext.Current.Items ) and cache the ChannelFactory used to create the channel per Application ( HttpApplication.Items ) since I can create more than one channel with the same ChannelFactory . However, I have a question regarding this cache mechanism when it comes to closing the

In WCF Client Architecture , it says When using the ChannelFactory class with a service contract interface, you must cast to the IClientChannel interface to explicitly open, close, or abort the channel So you create and use the client channel object like this: var cf = new ChannelFactory<ICalculator>(binding, ea); var channel = cf.CreateChannel(); double result = channel.Add(5.2, 3.5); Console.WriteLine(channel.GetType()); // outputs ICalculator Console.WriteLine(result); ((IClientChannel)channel).Close(); There are two things that confused me here. The method signaure of CreateChannel , as

I've got a hosted WCF service that I created a custom factory for, so that this would work with multiple host headers: /// <summary> /// Required for hosting where multiple host headers are present /// </summary> public class MultipleHostServiceFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { List<Uri> addresses = new List<Uri>(); addresses.Add(baseAddresses[0]); return base.CreateServiceHost(serviceType, addresses.ToArray()); } } I'm pretty sure that my config files are now right, on both client and server ( can be seen

So I've decided to up the performance a bit in my WCF application, and attempt to cache Channels and the ChannelFactory. There's two questions I have about all of this that I need to clear up before I get started. 1) Should the ChannelFactory be implemented as a singleton? 2) I'm kind of unsure about how to cache/reuse individual channels. Do you have any examples of how to do this you can share? It's probably important to note that my WCF service is being deployed as a stand alone application, with only one endpoint. EDIT: Thank you for the responses. I still have a few questions though... 1

Consider the following code which is typcial of many ChannelFactory examples: WSHttpBinding myBinding = new WSHttpBinding(); EndpointAddress myEndpoint = new EndpointAddress( ConfigurationSettings.AppSettings["HelloWorldServiceURL"]); ChannelFactory<IHelloWorldService> myChannelFactory = new ChannelFactory<IHelloWorldService>(myBinding, myEndpoint); IHelloWorldService proxy = myChannelFactory.CreateChannel(); ((IClientChannel)proxy).Open(); HelloWorldDataContract dc = proxy.SayHello(); ((IClientChannel)proxy).Close(); Note that when proxy.Open() is called, both the the channel's state and the
