C# Client server application (like msn messenger)

**TCP Socket Server (C#)** The socket server application needs to accept incoming connections from client applications. When a client succesfully connects a username/password needs to be validated from a database source to validate a client has access to the platform. The server application needs to read text messages from a database source and send them to connected clients. Each client has its own message queue. It would be nice if the server runs as a Windows service and also as a test application for testing purposes. The database is mysql 5 and should be accessed with a odbc driver. **TCP Socket Client (C#)** The socket client application is best described as a MSN LIVE Messenger-like application. It should automaticaly load in the system tray when a user logs on to Windows. When the client is successful connected to the server it should show text message alerts with a hyperlink so when clicked a browser windows opens with the url desscribed in the message. This application needs to have the following additional funtionality: - possibility to connect through a proxy server - skinnable alert window (with transparency) - logon automatically on application start - a mechanism for software updates
