How to Use SMPP to send SMS?

Question

Hi,

I am developing console application to send sms.

We are using thirdparty gateway to send sms.

Currently i am sending sms's using HTTP which is working fine.

Now we want to use SMPP to send sms, so i am developing console application which will use SMPP to send sms.

Can any body give me .net library for SMPP.

Thanks,
