Defining and Implementing a Contract
You will also need to have at least one transactional method as shown in the download. The zip file contains a generic helper class called EventsHelper that does just that. ChannelDescription object model The WCF Runtime is the set of objects responsible for sending and receiving messages. Using the ASP.NET compatibility features of WCF provides you with the SQL Server and state server implementations of ASP.NET session state to support enterprise-ready scenarios. The message contract defines specific message parts using SOAP protocols, and allows finer-grained control over parts of the message, when interoperability demands such precision.

In a way, the WSE2 messaging uses the IXmlElement plumbing interface for transferring objects to/from the XML formatted document; Indigo is using a MessageContractAttribute for controlling the insertion of custom headers and the body of the message during run-time. The demo uses the Service Fabric Remoting programming model for stateful actors. This resource address is used implicitly for the resource operation, so the client doesn’t need to know about its representation and it will use it as it is.
The demo contains IDesign's FilePersistenceProviderFactory and FilePersistenceProvider, which as their name imply, persist the state of the service into a file. Through the IIS Management Console, you can configure different rules when you want the recycling to happen. This is instrumental is advanced cases such as thread local storage and COM interop as well as advanced synchronization needs. A beginner would glance at the words and would think, well it is something which deals with Windows platform, which is used to communicate and connect applications. All behaviors can be applied imperatively by adding an instance of the behavior to the ServiceDescription (or the ChannelDescription on the client side).

The step-by-step process of how to consume a WCF service hosted in Windows Service is expressed below in detail with coding and instructions. Aaron frequently speaks at industry events including TechEd, PDC, and VSLive!

For enabling the transaction in the newly created method, it is attributed with TransactionFlow and transactions are permitted using is Allowed value. I suppose this might be used for the WSDL definition page or the help page.
The most common scenario is to define endpoints in a configuration file. For the client, I wrote the helper class ServiceBusDiscoveryClient, defined as: I modeled ServiceBusDiscoveryClient after the WCF DiscoveryClient, and itâs used much the same way, as shown in Figure 4. An Internet connection is required during the installation. .NET Framework 4 is required to run and develop applications to target the .NET Framework 4.

At Visual Studio Live in Orlando last week it was brought up again by presenter Leonard Lobel that while L2S is not dead there are no large investments being made anymore by Microsoft and eluded to this 2 year old article (and if this was 2 years ago, it is definitely has traction now) Update on LINQ to SQL and LINQ to Entities Roadmap: Member 13 Points Nov 22, 2010 08:47 PM|samw| Thanks very much for the ORM tips…………………….Now,Â can anyone tell me about WCF? The most important driver behind the robustness of your application is where/how you host your service. A tip which I want to share with our readers is that when you are declaring a DataContract or a ServiceContract and these terms don’t highlight (show error), probably because we haven’t included the required namespaces, we can do Ctrl+Dot key to implement the namespaces rather than by explicitly typing. In normal browsing, the server will record the relevant actions, including the IP address of the device you are using, the time of use, the browser you are using, the browsing and data logging, etc., As a reference for our website services. Transactions WCF also supports transactions using one of three transaction models: WS-AtomicTtransactions, the APIs in the namespace, and Microsoft Distributed Transaction Coordinator.
