Is it possible to pass generic objects (by generic I mean any with DataContract, not C# generic collection) without inheriting from one root? At the moment I have something like this: [OperationContract] void Save(GenericObject o); [DataContract] [KnownType(typeof(ClassA))] [KnownType(typeof(ClassB))] class GenericObject {.... [DataCo...

I created a REST webservice in WCF that originally used POST to perform any inserts and deletes. Mostly out of curiosity, I decided to change the insert to a PUT and the delete to a DELETE. While this worked fine on my local machine (using the built-in VS2008 webserver), I'm getting this error when trying to target an actual server dep...
We are migrating from Remoting to WCF a very big application that makes intensive use of DataSets. We use the ExtendedProperties of the DataSets' tables to store a graph of objects containing special information we need at client side. In our Remoting implementation we did add to the channel stack a client and a server channels to check...
I've written a simple Application that utilizes WCF to communicate between client and server. When I run it locally it works fine, however when I run the server and client on two different boxes I get the following exception: Unexpected error occured, while getting the group names from the VDN server System.ServiceModel.Security.Securit...

I have written a java axis2 1.4.1 web service and .net 3.5 WCF client and I am trying to catch the wsdl faults thrown. Unlike .net 2.0 the .net 3.5 claims to support wsdl:fault and the service reference wizard does generate all the correct fault classes in the client proxy. But when I try to catch a fault it doesn't seem to correctly s...
I'm writing a service that allows users to register with it and receive notifications when an event happens. I'm trying to do this with netTcpBinding, but keep coming up with errors, even when running on my local machine. When I try to send a notification, I am timing out, getting this error: Stream Security is required at http://w...
Is there a way to have a web service (WCF/ASMX/etc) call do some processing after it returns it's results? Note I'm not looking for a asynchronous calls as the client needs the result back ASAP, before the the extra processing is done. The primary constraint is that as far as I can tell, the only way for me to run code on my server is v...

I am implementing a WCF service (Contract A) that will eventually make calls to a standalone service (Contract B) hosted by the client. At design-time when the client queries my service's WSDL to build its proxy, I'd like to include the WSDL for Contract B so the client can build its service around that. Unfortunately, I can't figure out...
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.

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.

I'm using IDesign's ServiceModelEx assembly to provide additional functionality over and above what's available in standard WCF. In particular I'm making use of InProcFactory to host some WCF services within my process using Named Pipes.

We have a pretty large website, which handles a couple million visitors a month, and we're currently developing an API for some of our partners. In the near future, we hope to expose the API to all of our visitors. As we are trying to limit the number of requests to say, 100.000 / day and 1.000 / minute, I need to log the total number o...
Hi, I've been building a WCF app behind 3 projects (contract,implementation,client) I've hosted my service as a console app with basic HTTP binding. I'm now ready to move it to IIS. However, the tutorial for creating a .svc file shows it actually implementing the contract - but I already have an implementation. How do I just redirect to...
