 Hi.
This is good information:

Most of this is BT2004, but I think that also apply to BT2006.

I tried to develop my custom .net component the way it is described:

namespace Communicate.TimeDifference
{
    //[Serializable]
    public class TimeDifference : IFactCreator
    {

       
        public TimeDifference()
        {

        }

        public string PrintTestString()
        {
        return “Testing a custom .net component”;
        }

    //Then we are supposed to add this code (thay say…), in the same class

    public object[] CreateFacts(RuleSetInfo ruleSetInfo)
        {
            object[] o = new object[1];
            o[0] = new Communicate.TimeDifference.TimeDifference();//your custom class here
            return o;
        }

        public Type[] GetFactTypes(RuleSetInfo ruleSetInfo)
        {
            Type[] t = new Type[1];
            t[0] = new Communicate.TimeDifference.TimeDifference().GetType();
            return t;
        }

    }
}

I compile, put it in the gac, anf then using the PrintTestString() in a rule. But it will not fire.

I think I am into something here. Are we suppose to use Assert in the rule?

I am going to do more research on this now, and will provide any useful info!
