.NET MSN Messenger library

官方網站：.NET MSN Messenger library

引述官方網站的話：

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

不過它是使用 MSNP8 的，略舊。
