This issue has been moved from a ticket on Developer Community.

This is the result of 2 days of misery where VS would just kill itself at random times

THIS IS THE WORST RELEASE OF VS EVER AND IT HAS WASTED COUNTLESS HOURR FOR ME. FIX IT.

On top of all that, if I try to record the problem, it does not occur (but then again, VS now does not ask to restore recovered files anymore, so I guess the problem was in those files and I've lost all my work now ...)
