SuperSocket, an extensible socket application framework

SuperSocket is a light weight, cross platform and extensible socket server application framework. You can use it to build a server side socket application (like GPS server, GIS server, game server, FTP server, SMTP/POP3/IMAP4 server, SIP server, SNMP server, etc) easily without thinking about how to use socket, how to maintain the socket connections and how socket works.

It is a pure C# project which is designed to be extended, so it is easy to be integrated to your existing system. If your systems (like forum/CRM/MIS/HRM/ERP) are developed in .NET language, you must be able to use SuperSocket to build your socket application as a part of your current system perfectly.

The source code of SuperSocket also include some service implementation samples which you can follow.
