Asterisk and SIPClient GNU

Hi Everyone:
do anybody know any SIPClient on C# to operate with Asterisk? (With code) I have trying OfficeSIP but I cann´t connect. I found MicroSIP and is perfect but it was on C++.

C# doesn’t attract open source programmers.

· Yes, I think so, I prefer C o C++ but my job is on C#.

· Thanks
