We are developing a WCF based system. In the process we are trying to lock some data from being modified by more than one users. So we decided to have a data structure that will contain the necessary information for the locking logic to execute (by for example storing the ID of the locked objects) The problem we are having is persisting...

I've created a .NET WCF service that is intended to always be over HTTPS. When I first created the service skeleton and ran it over HTTP, it worked fine.

The server should host any WCF service (contained in DLL assemblies, loaded in runtime) that implements a minimal "plugin" API (StartService/StopService/GetStatus?/etc). This post is a go...

When using a Silverlight-enabled WCF service, where is the best place to instantiate the service and to call the CloseAsync() method? Should you say, instantiate an instance each time you need to make a call to the service, or is it better to just instantiate an instance as a variable of the UserControl that will be making the calls? T...
I have created a reference to an IIS hosted WCF service in my ASP.NET website project on my local workstation through the "Add Service Reference" option in Visual Studio 2008.

But when I step-thru t...

I guess it would have to be WCF based as I'm not sure that w...

The problem is that these services talk to another legacy application that uses a large CLR object as its primary means of communication. To keep...
