If you encounter this bug where your profiles or certificates don’t show up and it’s blathering on about FriendlyName can’t be set on Unix, it’s because the Mono version was bumped up to 6.x in Visual Studio recently and that’s affecting your build process.
To get around it, just go here and grab a previous version of mono.

I used 5.20.1.22 and everything was right in the world. YMMV
