We are implementing numerous services in our company and running into versioning issues with data contracts. One of the problems we have is that our data contract are also used as the model of the actual application behind the service. I was wondering what approach others have taken in this kind of situation or just service versioning in...
I'm trying to implement a service contract that contains a method which takes a generic interface, and that generic interface itself is given an interface parameter. I've decorated the service interface with ServiceKnownType, I have decorated the service implementation with regular KnownType, and I have decorated the datacontract impleme...
I'm pretty new to WCF and SOA, so I apologize if the question is poor. The way I see it, if I could specify a contract's Name and Namespace in app.config, I could change the service that my client contracts use at runtime rather than compile time. Without the ability to specify Name and Namespace in app.config, my client contracts are ...

Problem I would like to trace the Uri that will be generated by a LINQ query executed against a Microsoft.WindowsAzure.StorageClient.TableServiceContext object.

Hi, I have a quite simple WCF service method which returns an IQueryable, just for testing. Perhaps I got something wrong when trying to understand what IQueryable is designed for. I clearly plan to use this with the IQueryable provider of NHibernate later. But first I ran into some sort of serialization problems (at least I think it mi...
Hi all; I have an SL 4 application (with OOB and elevated privileges) which makes a connection to a secure WCF service. But WCF service is never called, the application waits to connect and afterwards timeouts. I have checked with fiddler and wireshark and I saw no connection is made, application just waits! As you know if elevated priv...

I have a self-hosted WCF REST application which is designed to accept and return JSON as a Stream with WebMessageBodyStyle.Bare. I am bypassing the DataContractSerializer using WebContentTypeMapper and WebContentFormat.Raw. It works fine locally via WebHttpBinding, and also works fine when I use WebHttpRelayBinding and Content-Type: tex...

If I call the service method from a web client, it works fine, but when I call it from the windows service, it fails every time and the error information doesn't give me anything specifi...
I'm installing a service on a machine that will call a method from another WCF service and email a rdlc report. I have the report being copied to the compile directory and I reference it so it seems to be finding it. LocalReport report = new LocalReport(); report.ReportPath = @"C:\Services\Exp...
From the little that I know about WCF it seems to be the right solution to a particular problem I have but I'd like to get some input on it. Problem Description: Clients sequentially access domain objects from a list roughly once ever 1-10 minutes (average is 2 mins), but no 2 clients should ever access the same object. Certain orderin...

As many of you will be aware, I can use the DataContract attribute to mark a class for serialization into XML in a WCF service. For example, I can create a DataContract thus: < DataContract() > Public Class fooClass < Datamember() > Public fooString as String End Class When I add a service reference to the code that wi...
