I am trying to access and use the SmarterTrack API from within a webforms asp.net application. Specifically reporting on application errors thrown and caught in the global Application_Error event. I have created a separate assembly that has the webservice code automatically created by referencing the API Service and use PingService and other API methods.

I'm open to suggestions as to how to get this working :-)
