Send data from unity to windows form application using named pipe?

I tried Implementing this: http://wiki.unity3d.com/index.php/Webservices_In_Unity. I could get data from wcf host to Unity app. But I want to do exactly reverse of this. I want to send data from unity to Windows Form using namedpipes. I also tried to implement this: https://dopeydev.com/wcf-interprocess-communication/ in above method. Although i could create proxy class script. I was unable to host a server from unity that could send data from Unity build to the client Web Application. All i want is to create a wrapper DLL that can be implemented in any application which runs on same desktop. I have tried Interprocess communication methods, but examples could only limit data sent to unity app , and not data sent from unity app This DLL accepts data which is sent by Unity App and then can be received by Clients app which he/she makes at his side.

Any resource or help is mostly appreciated. Thanks in advance
