I am fairly new to Sage, went through the Object Interface class at SageU.com. While running the example I am getting an error <NewObject: 200> whenever there is a call to Invoke Method on "AR_Customer_svc".

Using Win 2012 Server, Sage 100 - 2014 with Visual Studio 2013 C#. Any help / pointers. "Allow External Access" is enabled.

Error details:

Code -
using (DispatchObject ar_cust_svc = new DispatchObject(pvx.InvokeMethod("NewObject", "AR_Customer_svc", oSS.GetObject())))

Here is the error -

System.Reflection.TargetInvocationException was unhandled
