We can use polling to find out about updates from some source, for example, clients connected to a webserver. WCF provides a nifty feature in the way of Duplex contracts, in which, I can maintain a connection to a client, and make invocations on that connection at will. Some peeps in the office were discussing the merits of both solutio...

I need some direction related to this topic; maybe I am missing the obvious. I dont see a contrast between WCF bound to HTTP and strongly typed web service. Why would this be any different?? I agree there are some development nuances especially related to XmlSerializer in ASMX vs WCF and a plethora of Microsoft jargons. Short of these;...

I have to do some maintenance on a WCF service that is hosted in a managed windows service. In the old deployed version I can enter: http://localhost:9091. It shows a page with info about the hosted WCF service (with a C# and VB example). When I get the sources from TFS and reinstall with the MSI, the same http://localhost:9091 gives a...
I have a very simple WCF service that I would like to expose publicly. I created the service and set it up over our server without much hassle. The problem is that we are able to use the service from within our private network, but when we attempt to use it from outside the network, the following error is throw: “The Security Support ...
Hi, I have a client-server system, both sides written by me, and I would like to put the clients in an 'offline' state when the server disconnects/dies, and then automatically bring them back 'online' when the server is available again. For the first part, I listen for channel faulted events and handle that by setting the client to off...
