Please recommend PDU SMS format code or library for .NET or C++

I have been searching a lot for a chunk of code, or a library to format SM开发者_如何学JAVAS messages in PDU format and had little luck. They were either huge monsters with terrific dependencies on everything way above my requirements and a very obscure interface, totally not justifying the straight-forward, although rather complex encoding.

Being on the edge of creating a NIH, my question is - have encountered the same problem and how have you solved it?

GSMComm has a PDU conversion class for wroking with SMS Messages.

I use this library to encode and decode messages. It also works with multi-part messages.
