Our WCF web services

Our WCF web service is going to expose two functions to return data to the client and one routine to add a message to the queue when an order status is updated on the client.

ERP service interface — IERPService.vb

These following functions and routines will be exposed when the service is called from the client. This is our code in our IERPService.vb file, in the WCFWebService1 role:

Imports System.ServiceModel
NOTE: If you change the class name "IERPService" here, you must also update the reference to "IERPService" in Web.config.
