WPF TCP/IP Chat - 05/06/2018 05:23 EDT

I need a Chat Application, Frontend and Backend as an autostart service. On the Frontend users are selected from a combobox which is filled from a user table from a Database, the password is written and the user is loging in. Before the login to occur it is proofed if the user has a password in the user table and when it has if the password is correct or not. For each case should show errors( Password missing, Password wrong). When a user has logged himself, the app should show him a welcome dialog box with his name and should minimize its self in the System Tray and with a doubleclick event it should appear on the desktop, the user it should also be able to change his profile picture and to set his status to Online, Offline, Busy. The implementations should be, beside sending messages of course, a snipping tool, file transfer, print the conversation and save the conversation local. I should be able to see my chat history not older than a week, also it suppose that the conversations should be saved on the Backend in a table and after seven days automaticaly deleted. Each message should also have sending timestamps.
