If I set listenBacklog="10" I am able to telnet into the port where my WCF service is running. If I change listenBac...
I have been tasked with creating a set of web services. We are a Microsoft shop, so I will be using WCF for this project. There is an interesting design consideration that I haven't been able to figure out a solution for yet. I'll try to explain it with an example: My WCF service exposes a method named Foo(). 10 different users call...

Hi guys, I'm trying to get WCF to use SSL with ANYTHING for FIVE DAYS now. I've gone through countless walkthroughs, generated more certificates than a mail order diploma company, even tried hot fixes. After working with MS dev tools since VB1, I am now considering flipping burgers as a career option. WCF, as far as I can see, is a comp...

For historical reasons, I have some WSE 3.0 web services that I cannot upgrade to WCF on the server side yet (it is also a substantial amount of work to do so). These web services are being used for file transfers from client to server, using MTOM encoding. This can also not be changed in the short term, for reasons of compatibility. Se...

What is the best way to pass an existing SAML token from a website already authenticated via a passive STS?

Hi, I am a .NET developer with no coldfusion experience, but I need to write cf code to access a wcf service i've set up. I've got a few WCF services being hosted in IIS 7 with WsHttpBinding, and I'm able to use the services fine by adding service references to a .NET client and using client classes. It is very straightforward for a ....

I'm seeing some unusual behavior when using the DataContractSerializer. I have defined a message contract like so: namespace MyNamespace.DataContracts { [MessageContract(WrapperName = "order", WrapperNamespace = @"http://example.com/v1/order")] public class MyOrder { [MessageBodyMember(Namespace = @"http://example.com/v1/order", Ord...

It's only alluded to and not actually defined though. Can someone give me a good explanation of what Dublin is? Also, what is its release status and is it going by a different name now? (H...
I've given a fair read through msdn:datacontracts and I cannot find a out why the following does not work. So what is wrong here? Why isn't ExtendedCanadianAddress recognized by the datacontract serializer? Type 'XYZ.ExtendedCanadianAddress' with data contract name 'CanadianAddress:http://tempuri.org/Common/Types' is not expected. Add ...

For a simple parent-child relationship, the solution is pretty simple with .NET 3.5SP1 or greater - the IsReference property of a DataContract (this page has a good explanation). However, my relationships are three levels deep: grandparent <-> parent <-> child. A "grandparent" has many "pa...
