Heya Leonsito,
Welcome to our forums and many thanks for your interest in our network library.
If you right click on the project in VS2010, and select properties, can you please confirm what the target framework is?
The .net3.5 dll and .net2.0 dll are identical. So if using the .net 2.0 version fixes the problem I wouldn’t worry about it any further.
Regards,
Marc
