[flexcoders] Flex Webservice for .NET - converting to C#

[cjsteury2]

I need to re-write my Flex app for C#.. this webservice will not run in VS2005, 
and I am pulling my hair out (not much left!).  Does anyone have an idea why I 
get this error

System.NullReferenceException: Object reference not set to an instance of an 
object at VTResults.GetResult()

This is a SQL query for DataSet that then serializes to a Class as Data Model 
for Flex.
