This MSDN article recommends always to provide a namespace to a ServiceContract and DataContract. Examples usually have a "schema" prefix and a URI type pattern for the namespace such as Namespace="urn:WCFEssentials/Samples/2008/12" instead of a traditional C# namespace with dot-notation such as Namespace="MyNamespace.MyDataClasses" What is the suggested format the namespace property? Do we need the schema prefix? Why is this format suggested? It's an XML Namespace . Those can either be in the urn: format or they can be URLs. Here are some additional suggestions from MSDN : The namespace can

The program I am working on exposes both callbacks and services using wcf. Basically, what the services do is simply return some variables value. As for the callback, they simply update those variables. I want to be able to expose one class containing only the services and one class containing the services and the callbacks. For example : [ServiceContract] [ServiceBehavior(InstanceContextMode=InstanceContextMode::Single, ConcurrencyMode=ConcurrencyMode::Multiple)] public ServiceClass { [OperationContract] public int getValue() { return mValue; } protected static int mValue; }; [ServiceContract

I've got a working WCF interface using more than 100 ServiceKnownType in the contract like this: [ServiceKnownType(typeof(RowUser))] [ServiceKnownType(typeof(RowRegion))] [ServiceKnownType(typeof(RowDocument))] [... loads more ...] [ServiceContract(SessionMode = SessionMode.Required)] public interface IServiceBrowse : IDisposable { [OperationContract] void Insert(Row satz); } Is there any way to provide these ServiceKnownTypes during runtime? It is not only error-prone and tedious to add all these ServiceKnownTypes in the source, it keeps my assemblies tied together in a way I don't like (I'd

I have declared two service contracts as follows: [ServiceContract] public interface IContract1 { [OperationContract] double Add(int ip); } [ServiceContract] public interface IContract2 { [OperationContract] double Add(double ip); } I have a class which implements these two contracts. I have created two endpoints for both contracts. But I'm not able to access the service from client code. It displays a big error when I try to update the service reference as: Metadata contains an error that cannot be resolved.... There was no endpoint listening at ... , etc. I know that you can't have two

I was curious if someone could outline which types of WCF contract (interface) changes on the server side would break a client trying to send in a message, and why. I believe WCF can handle certain discrepancies, but I'm not sure exactly what you can change safely, and what you can't. Add/remove parameters from an OperationContract? Add/remove/change the DataContract's serialized properties? Add/remove OperationContracts from a ServiceContract? A friend asked a similar question here: Does adding a method to a WCF ServiceContract break existing clients? EDIT: As John Saunders pointed out,

Greetings, I would like to generate some contract based on wsdl file. I used svcutil but I suspect it generated it wrong as all contract methods have void returned type. Is there any tool for this purpose? EDIT: here is the wsdl file: <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:tns="http://dantek.com.pl/EDItEUR/EDItX/LibraryBookSupply/WebService

How can I write a WCF web service that has single endpoint but multiple service contract? Example: [ServiceContract] public interface IWirelessService { [OperationContract] void AddWireless(); } [ServiceContract] public interface IWiredService { [OperationContract] void AddWired(); } [ServiceContract] public interface IInternetService { [OperationContract] void AddInternet(); } Lets think like IInternetService is my main webs service and i want to implement IwiredService and IWirelessService in it, but i want to do implementation in their classes.Is this possible? How can i solve this problem?
