I have a Windows Service application that checks a queue for data
import requests. Everything works fine 90% of the time, but
occasionally the .Net runtime crashes, reporting in the event viewer
"Application has generated an exception that could not be handled".

My question is related to the ExecuteInMainThread property. Does this
have to be set to true in VB.Net just like it was for VB6?

Given that the thread that initiates the DTS request is a pooled
worker thread from my service application, I am suspecting that it is
a issue with my DTS threading settings that is causing this problem.

Any suggestions are welcome.
