This is known issue and we have notified the Mono team
https://bugzilla.xamarin.com/show_bug.cgi?id=29499

[miguellira]

Thanks @suhasj.

Is there a preferred DNVM/Mono combination at the moment? Since the mono Homebrew formula has been updated to 4.0.1 is there a recommended way to get a stable environment to build/run the samples?

/cc @glennc

I am not sure of this since I have hit issues with both 4.0.1 and 4.1.0

[javi830810]

Same issue here, mono 4.0.1 and dnx 4.5.1, please advice

[davidfowl]

beta4 + mono 4.0.1 and 4.1 have this issue and there's no known workaround.

[ThorstenHans]

Issue also appears in the following combination
Mono 4.0.1
dnx and dnu 1.0.0-beta5-11649
dnvm 1.0.0-beta5-10371

FWIW...

If you, like me, decided to uninstall Mono 3.x after installing 4.x and will like to get back to a somewhat stable state. You can unlink Mono 4.x and reinstall 3.x by doing the following:

brew unlink mono
brew install https://raw.githubusercontent.com/Homebrew/homebrew/68a18ac660515e313cd175c550e3065320dfadec/Library/Formula/mono.rb

Unfortunately, all of the issues that exist with running Mono 3.x and the latest DNX will continue, but at least you'll be able to play around with Visual Studio Code on Mac :-)
