I am creating a WCF Service that will be consumed by both .NET and Java client applications. We do not have any Java experience in the team, so are looking for guidelines or rules to follow to ensure that we do not accidentally include any types in our WCF Service interface or do anything else that would preclude it from being consumed ...
The contract name 'IMyService' could not be found in the list of contracts implemented by the service 'MyService'.. ---> System.InvalidOperationException: The contract name 'IMyService' could not be found in the list of contracts implemented by the service 'MyService'. This is driving me crazy. I have a WCF web service that works on my ...

What do I do in order to fire an event when a new client connects to WCF-hosted service? EDIT: What I'm looking is to get an event when a new session is created or new Channel gets created for a client. Such as: for session closure I'm using: OperationContext.Current.Channel.Closed += new EventHandler( Channel_Closed ); so what shoul...
Just like the title says. Does each authenticated WCF client connection to a WCF server that you have developed need a windows CAL? http://www.microsoft.com/windowsserver2008/en/us/client-licensing.aspx Microsoft's licensing on that page sure makes it sound like it, but I can't find anything out there that confirms, or even denies thi...
We are developing a project that involves about 10 different WCF services with several endpoints each. One of the services keeps a few big tables of data cached in memory. We have found we need access to that data from another service. Rather than keeping 2 copies of the cache, I'd like to be able to share those tables across all servi...
I'm trying to get hold of an object from another application using WCF. With built in classes it works fine but I run into probems when trying to return a custom interface type from the WCF operation. Whether I include the interface in both applications separately, or specif it as a shared assembly, I get the same result: a Communicati...
We have a C# WCF service (3.0) that takes in data and then make another web service call to a third party with that same data. Before the third party call, the entry data is saved as a record in a database, and then updated with response data from the thrid party web service. We have start doing some Load/Stress testing, and noticed th...

My question is in regards to the best (aka "least painful") way to secure access to a WCF service that is only exposed to our company's internal users. The goal is to ensure that the service is only accessed via a single windows forms application that each of our users has installed. When the service is called, I want the service to be a...
Does a WCF service on SharePoint require that Anonymous Access is enabled? We have an application page which is calling the service using Ajax.Net, if Anon Access is off then we get prompted for the username and password, if it is on then all is well. We are not using a WCF client, it is purely being called by the scriptmanager <confi...
Sorry, but I am not sure what causes the problem, and the problem isn't happening right now. I'll have to describe from memory. So I've started creating WCF Service Applications. Sometimes, when press F5 to run the project I get the correct screen, a screen that says: Service1 Service You have created a Service. To test this service...
My application is using the net.tcp WCF service with a callback channel. For some reason I'm not able to send callbacks on event. Here's what I'm doing (all code server-side): On initialization: OperationContext Context { get; protected set; } ... Context = OperationContext.Current; On event: var callback = Context.GetCallbackChanne...
I have a Windows Service which is basically accessing a mailbox and reading the emails. I am trying to figure out the best way to check the mailbox every x seconds. One method is to just call Thread.Sleep, then call the Start Method again, e.g. protected override void OnStart(string[] args) { // get config settings CheckMailb...

I have a web application that exposes web services using WCF and wsHttpBindings. It is possible to have the application on different machines and different urls. This would mean the WCF service location would be different for each. I am building a Windows Service that will reference each application and perform a task. Each task needs t...
I have a standalone (non-IIS) WCF service that - besides the services - provides some simple HTML pages via a WebServiceHost. When I enter http://localhost:1234/SomeRandomWords as an URL into the browser I get a default error page that says Dienst Es wurde kein Endpunkt gefunden (Translated to english: Service / Endpoint not found) ...
