[OpenBabel-scripting] Problems with OBDotNet

[Bob T. <Bob...@co...>]

I'm having some troubles with getting OBDotNet to work and am hoping for some help. I have OpenBable-2.2.0 installed and am using VS 2008 sp1. I made the simplest program

using System;
using OpenBabel;

namespace OpenBabelTesting
{
class Program
{
static void Main(string[] args)
{
OBConversion obc = new OBConversion();
}

}
}
and when I run it I get this exception:
System.TypeInitializationException was unhandled
Message="The type initializer for 'OpenBabel.openbabelPINVOKE' threw an exception."

I thought it had something to do with openbabel.dll but I could not add it as a reference to my project or the GAC. Any ideas?

Thanks in advance,
Bob
