I have just released the first version of Bebo.NET. It is written in C# for .NET 2.0.
Bebo.NET is a set of .NET class libraries which can be used to wrap calls to the Bebo.com APIs. It is based on Nikhil Kothari's Facebook.NET project.
It is hosted on CodePlex and you can find it here. It is a straightforward port of Facebook.NET and so any documentation relatiing to that project is pertinent to this one. Bebo might have some differences that have not been considered but, as this project is now open-source, hopefully other developers will take up the torch and carry it forward. I will be updating it on a regular basis as I am spending a lot of time, at the moment, writing applications for Bebo.
I spent a lot of time looking around for other projects like this but since Bebo is not as popular as Facebook there hasn't been much to go on. So.. I hope this helps those that are interested.
