Issue/Introduction

Symptoms: 

The customer reported that they are using the .NET generator to consume imported web services.

The calling of one of the two web service was working fine, but they got an application error when they called another function in the same dll.  If they always execute the same function, it works fine. If they execute the first web service and then the second web service, they get this error:
