Provide better debugging information in .NET exceptions

[CurtisHx]

The information provided with exceptions has not been useful in determining the problem cause.  For example, the latest bug I've been dealing with in my code involves 2 tasks trying to access the same resource.  The exception gives the name of the task that throws the exception.  Great.  It's really easy to tell which task throws the exception because, well, it's throwing the exception.  What the exception message doesn't tell me are the other task(s) that have that resource.  The really useful information is consistently lacking in exception messages.
