The last stable VS studio release hangs the VS IDE after one compile, the subsequent Alpha release fixed that but you could no longer set a breakpoint.
In the stable release you still have no breakpoints rendering the product useless as you loose one of Xamarin's major USPs, iOS barely works now and is incredibly unstable but breakpoints work after a fashion.
There is a limit to peoples patience when your paying $1900. Seriously.......utterly fed up with Xamarin at the moment.
There seems to be a wall of silence from Xamarin, same applies for Forms.
