Based on the last line, I’m really surprised that don’t have error reporting on by default for all pre-RTM builds (although maybe it was on in the beta and they turned it off for the RC).
Checking the compiler options, it looks like I should have gotten a prompt but didn’t.
However, I then ran Fiddler and ran the build again (causing another crash) – yup, the watson reports are getting sent in just fine. Kinda surprised I didn’t get a prompt, but that may just be a bit they set to always send if it’s a pre-RTM build (which would be reasonable IMHO).
