First of all, thank you for reading this and I hope that you can bear with me. I have a rather complex problem here and I am about to turn to Microsoft for some answers. I have written a WCF service that implements the FlexNet API to automatically search an update server for product updates, and installs them on a client's machine if an...
Is Duplex Binding supported in windows Workflow Services and WCF integration? Can an activity "register" with a WCF service and then can a WCF service raise an event to the registered activity in the workflow when it needs to? ...
I am developing a solution with multiple WCF services which all communicate among themselves, even though they are of different types. The services connect to one another through the ChannelFactory generic interface, and every service is hosted inside a ServiceHost. My question is if it would be correct to use a callback contract among ...
Hi Folks, I have created a web application with a Silverlight project embedded in it, using VS 2008 SP 1, and the Silverlight 3 tools, on Vista and Windows 7. The duplex service code: [ServiceContract(Namespace = "cotoco", CallbackContract = typeof(IDuplexClient))] [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)...

First, the server invokes some function Foo on the client which then forwards the request to a Windows Forms GUI: GUI CLASS delegate void DoForward(); public void ForwardToGui() { if (this.cmdSomeButton.InvokeRequired) { DoForward d = new DoForward(Forwa...
I have a Word 2007 document with many sections. Each section enables / disables duplex using a PCL5 escape code in the header on page 1 of the section. PCL5 printers are getting rarer, especially high volume / capacity ones. Is there an equivalent generic code that could be used instead of a printer specific code? Or is there a PCL6 ...
I need to create a WCF service (duplex, because it's also about Silverlight and a lot of localhost - stuff, it's a very complicated, legacy - bound situation here...) which will accept multiple sessions, is able to send notifications to multiple clients, and nothing must be blocking. So my first attempt was to create a class that employ...
Hello I'm following this brilliant piece of article to dissect and understand chat using WCF. The logic is that when a user joins a chat an event handler is created for that particular user and is stored in a dictionary. lock (syncObj) { if (!checkIfPersonExists(person.Name) && person != null) { ...

I am using the polling duplex model for my silverlight app and wcf communication. The wcf service pushed data to the silverlight app. While the app runs perfectly in my local environment and local iis (xp, iis5.0), it has a very unpredictable and abrupt behavior when i deploy it on my test server on IIs 7. The default for the 'ServerPo...
