Issue/Introduction

.NET Agent does not provide complete information about the frontend of the our application. 

We see several requests going to the server through AXA, but these requests are not seen on the agent side.

.NET Version 3 

Resolution

Using JetBrains dotPeek, found an issue in the instrutmentation.  ASyncStateMachineAttribute is the instrumentation that is needed.  Added to MVC.pbd.
