WCF如何服务于通信渠道？

Question

My project requires me to execute a windows service that performs some back-end operations while a WPF GUI displays information to the user and also allows the user to do some configurations. To be more precise my back-end service performs anti-malware operations indefinitely while the GUI needs to communicate with the service to fetch data and for enable/disable operations.

Now for this communication between the GUI and my service I researched on this forum and majority of people suggested using WCF service hosted in my original service. I have done just that, hosted a WCF service in my back-end service Onstart() function. My GUI is also able to reference the WCF service and the buttons can call the WCF hosted functions.

Now I don't understand how WCF will communicate with the service that is hosting it. This is because the purpose of using WCF was to build a communication channel between the GUI and my original windows service. I want to expose the windows service functions to the GUI and not those I have written in the WCF service. I have researched a lot and cannot find relevant articles. Someone please help me to call my windows service function when a button is pressed on the GUI. If there are articles already existing please refer me to them. I am short of time and any help will be highly appreciated.

Answer 1

If your WCF service should call your windows service's methods and they are in different assemblies, the easiest way might be to extract the methods you want to call from the windows service in an interface. Put that interface into the WCF service's assembly and take one such object as constructor parameter for example. Then work against that. Reference the WCF service assembly in your windows service, and pass the service to the WCF service after you have made the windows service implement the required interface.
