What is dotMSN ?

dotMSN is a class library to make use of the MSN Messenger Service. The library is built in C# and can therefore be used by all languages the .NET environment supports. DotMSN provides an easy and consistent interface through a clean Object Oriented approach. DotMSN abstracts the low-level MSN protocol so you can quickly integrate dotMSN with your application and make direct use of MSN-connectivity. DotMSN is free and can be used in both non-commercial and commercial applications. The library can, among other things, be used for:

• MSN bots
• Sending application-notifies
• Self-made clients / webclients
• Integrating contact info with your application

Ofcourse there are more possibilities, if you have an awesome idea, just download the library and happy coding!

Update: although the latest release is dated April 2004 we have been working on DotMSN ever since. A whole new framework has been build and will be released soon! This release (2.0) will include many new features and a more extensible and stable foundation. Visit this site regularly to stay informed! (11 jan 2005)
