But when I try to execute following script it is giving InvalidProgramException. Please do needful to me:

string scriptData = @”function ShowMessage(){ var a = new SayHelloClass();
a.SayHello(); // This is giving invalidprogramexception.
}

C# code is:

public class SayHelloClass()
{
public SayHelloClass()
{
}
public SayHello()
{
MessageBox.Show(“Hello!”);
}
}

I’ve registered global settings as follow:
JintEngine engine = new JintEngine();
JsConstructor ctor = engine.Global.Marshaller.MarshalType(typeof(HelperClass));
((JsObject)engine.Global)["HelperClass"] = ctor;

and calling the ShowMessage API as follow:
engine.Run(“ShowMessage()”);

I’ve tried to debug and it is giving exception from NativeMethod.cs class:
visitor.Return( m_impl(visitor.Global, that, parameters) );

What Am I missing here? Does it due to reflection limitations? How can I overcome to this problem?

Thank You,
