PGP Automation in C#.NET - 64 Bit

Question

This is for .NET 2.0. Is there any simple solution to automate PGP Encrytpion and Decryption in 64 bit dll. I used the OpenSource dll (NSDPGP) but i have issue in 64 bit. I think so they dont support 64 bit. I got some other solution but i dont want to use Command Prompt options, because catching exceptions regarding the issue is a problem. Looking for a solution ASAP, thanks for your time.
