Looks like you need to update your mono version.

i tried upgrading the mono version with brew, my current mono version is below, but still the same issue.

Yea that's beause it's still a super old version of mono. I'd suggest trolling through the many threads on aspnet/Home or search for how you update mono to the correct version.
