@jeffreytan81 I think the callout for multiple exception is a good question. I made a C# testbed to see what would happen if I had multiple simultaneous exceptions.

When manually collecting a minidump on my Windows system and then viewing it, I do get a warning that my application has multiple exceptions.

This leads me to believe multiple exceptions is acceptable, albeit rare.
