Contents Note: The Workflow test case requires installation of the .NET Framework 3.5 (Orcas) Beta 2 version. Features Input/Output (One way) Request/Reply Duplex Session Transactional Sync and Async connectivity fashions No Encoder Introduction The Microsoft Windows Communication Foundation (WCF) represents a logical model of connectivity, where the connectivity between the service and its consumer is abstracted to the stack of the channels on top of the physical transport layer. Based on the binding stack elements and physical transport on both ends of the connectivity, we can define how the message can flow between the business layers in terms of the message exchange pattern (MEP). The business connected layers represented by the client (proxy) and service can live in the same appDomain or on the different appDomains in the same process, out of the process or across the machine.
This article is focused on the WCF connectivity model within the same appDomain. Test Test_Workflow. Dan Rigsby. Posted by Dan Rigsby on January 19th, 2008 I have been working pretty heavily with Wcf over the last couple of weeks and really dived into understanding the ABC’s (Addressing, Binding and Contracts) of Wcf. If you dont already know, Addressing and Contracts are very straight forward. An Address is the uri string and the contract is the name of the interface that the endpoint implements. Binding is a quite a bit more difficult to understand and get right. *Doesn’t use a WCF message encoding – instead it lets you choose a pre-WCF serialization format Notes: Items in bold are the defaults for features that have multiple values. “–“ = No Support Abbreviations : WS-SC = WS-SecureConversation, WS-SP = WS-SecurityPolicy, WS-A = WS-Addressing, WS-AT = WS-AtomicTransaction, OleTx = OleTransactions.
WCFMock, a mocking framework for WCF services - Pablo M. Cibraro. WCFMock, a mocking framework for WCF services. Not a very original name, but it was the first one that came out to my mind :). If you have been following my blog for a while, you might notice that I discussed different approaches in the past to unit test WCF services, here and here. One of the major pains that you will find today for unit testing WCF services is the static operation context (OperationContext and WebOperationContext). If you service implementation relies on that context for doing something, you will have a hard time trying to test that functionality. For instance, it is very common in WCF REST services to use the context to set or get http status codes. Let's see how WCFMock works in practice with a very simple example, 1.
[ServiceContract] public interface IProductCatalog [WebGet(UriTemplate = "? [OperationContract] Atom10FeedFormatter GetProducts(string category); public Atom10FeedFormatter GetProducts(string category) var items = new List<SyndicationItem>(); Authors = 2. 3. The Problems with WCF and the Using Block. WCF Clients cannot be used inside a Using block because they may unexpectedly throw an exception. And even if you catch the exception, it is possible that a connection will be left open. We look into the history of this issue and some proposed workarounds. The corner-stones of resource management in .NET are IDisposable and the Using block. Aside from CLR objects, the lifespan of everything in the .NET world is managed using these tools. So one has to wonder how Microsoft managed to fail so miserably with the WCF framework. The first problem with WCF clients is that the Close/Dispose method can throw an exception. Even worse, there is a chance that the Close/Dispose method can leave the connection open if Abort isn’t called.
In a newsgroup thread dating back to 2006, Brian McNamara gives us the back-story on the design flaw. Workarounds Steve Smith has proposed a CloseConnection extension method. Finally there is the WCF Service Proxy Helper class from Erwyn Van Der Meer. WCF TCP-based File Server. Free source code and programming help. Download source code - 21.1 KB Introduction This article shows you how to build a remote file store using WCF. Specifically: Using TCP binding to stream files to a client from a storage location Connecting to the server from a WinForms client Implementing the ability to download, upload, and delete files from remote storage Configuring both server and client for streamed TCP transfer Background There are a few reasons why you might want to create such a remote file store; one of them might be because you have several applications which need to share files which have been uploaded by a system user and then access from a separate administration system.
Using the Code In this section, I shall detail the sections of code which are relevant to the topic, starting with an overview of the service itself. The Service The operations which our service will provide are as follows: Downloading a file Uploading a file Deleting a file Listing the contents of the file store Service Implementation The Client.

Windows Communication Foundation (WCF) Windows Communication Foundation (WCF) is a dedicated communication framework provided by Microsoft.
WCF is a part of .NET 3.0. The runtime environment provided by the WCF enables us to expose our CLR types as services and to consume other existing services as CLR types. Background: In the world there are a lot of distributed communication technologies that exist. Some of them are: ASP.NET Web Services (ASMX) Web Services Enhancements (WSE) Messaging (MSMQ) .NET Enterprise Services (ES) .NET Remoting Creating and Consuming a Sample WCF Service: Three major steps are involved in the creation and consumtion of the WCF services.
Create the Service. In WCF, all services are exposed as contracts. Service ContractThis contract describes all the available operations that a client can perform on the service..Net uses "System.ServiceModel" Name space to work with WCF services.

WCF : A few tips. Free source code and programming help. Download demo project - 52.7 KB Introduction I am by no means a WCF expert, but I have been using it a bit at work of late, and I have come across a few issues that I thought may be worth mentioning in as a top-tips style article.
So that is what this article will be. This article assumes you know a little bit about WCF, and that you know enough to edit config files. Please make sure to read the "Running the code" section before you try to run it. Tip 1: Debugging WCF One of the first things that you will most likely want to do is call a WCF Service and debug it. The attached demo app uses a Console hosted (self hosted) WCF Service, which is hosted as follows: So this is enough to host the WCF Service.
Tip 2: Adding a Service Reference If we consider how the attached demo app WCF Service is configured at the server end: It can be seen that there are three possible end points: netTcpBinding HttpBinding MexBinding and two possible host addresses: Amendment So thanks Benoît. Tip 3: Service Configuration. Windows Communication Foundation: Application Deployment Scenari. Michele Leroux Bustamante, IDesign May 2008 Windows Communication Foundation (WCF) is Microsoft's platform for SOA.
It is a rich technology foundation designed for building distributed service-oriented applications for the enterprise and the web that are secure, reliable, transactional and scalable. WCF Releases and Platform Support .NET 3.0 was released to manufacturing in November 2006 and officially launched with Windows Vista in January 2007 – introducing WCF along with Windows Workflow Foundation (WF) and Windows Presentation Foundation (WPF).
With .NET 3.5 – launched with Visual Studio 2008 in November 2007 – additional WCF features were introduced including: Built-in support for web programming models such as Plain Old XML (POX), Representational State Transfer (REST), JavaScript Object Notation (JSON) and syndication feeds such as Really Simple Syndication (RSS) and ATOM. A Platform for SOA WCF was built with SOA in mind: Unified Programming Model Flexible Hosting Model Protocol Support.
