Employee Locator v2.0 System

This was the last system that I have developed using C# WPF for our Software Engineering project. So this system basically allows all the employees in a certain office to communicate to each other: chat and send/receive files via TCP/IP. Meaning, requires no server. Of course, I'm not the one who developed the libraries.

This is the main interface. It needs a database though, since I wanted it to be like a Facebook office version. I'm the backend and the frontend designer/programmer of this project, but I need to thank my group mate who is good in photoshop, he designed our logos and icons.
