Answer 1

You can't catch all exceptions. There's a few assumptions in your example. You are, for instance, assuming the exception was raised on the calling thread. Catching unhandled exceptions on other threads depends on which runtimes you're using (console, winforms, WPF, ASP.Net, etc).

Additionally, calls to System.Environment.FailFast() do not generate any handlable condition - the process is effectively terminated with no chance for intervention.
