I've hosted an WCF service in SharePoint 2010 (basicHttpBinding) using this tutorial. The assembly is deployed to the GAC and contains the WCF service and a timerjob. Both call the same method.

Despite using many sql databases before, I've never actually tried to develop an app with a database in the App_Data directory. Until now!! It's a small WCF service project, which has a sql express 2008 r2 database. Working in VS there are no problems, I thought it would be as easy as deploying to a server (win 2008 with sql 2008 r2 i...
Folks, I am building a RESTful service that is secured by providing an XMLDSIG XML signature at the bottom of the XML document. When I send this document to the server, the WCF service is doing the XML de-serialization method on the HTTP payload to give me a C# class. Unfortunately for this de-serialization to occur properly, the C# cl...

Hi, I have developped a custom WCF Web Service within a SharePoint 2010 Visual Studio empty project. My web service is working well. The problem is related to the size of the request I can send to this web service. I have realized that is something around 300Kb.

The workflow aggregates WCF services and is triggered by a Receive activity that is in turn spawned from a Web page. While the workflow is being executed, the user's Web session is active, and certain workflow activities may need to inform a user, i.e. W...
I'm generating a WCF service using the message contract model. I have created a generic request message contract like so: [MessageContract] public Request<T> { [MessageBodyMember] public T Details { get; set; } } I'm used to using [DataContract(Name="Contract{0}")] to produce readable names for generic data contracts, but thi...

I'm fiddling with a wcf service, and I've created a simple test one. When I 'run' the service, I get a directory listing in ie of the folder that the service is in. I can click on the 'myservice.svc' and it brings me to the page I'd expect, so that's ok. I get the eerie feeling that this is wrong. Is it? If so, how is it fixed? ...
We are developing an application that needs to be executing on a periodical basis (e.g. daily, or weekly depending on config). This application needs to consume existing WCF Services but this application itself does not expose any methods for others to consume. What would be the most suitable (and future-proof) technology to use for t...

Hi, Does anyone have a good example for common error handling for service calls? I just started a new project and I see a lot of duplicate code that I don't like and would like to get rid of. I manage to do so in several other layers but in the proxy layer making the calls to services it is a little bit harder. The code is basically str...

Except that one of my QA guys has deleted the certificate from his client PC and he can still connect to the service. This leads to my question: In Internet Explo...
