I just wanted to chime in, I spent the afternoon installing VS2017 Preview with a view to trying out the Xamarin Live Player. Once I had put the Windows laptop on the same wifi network as my dev Samsung A3 and iPhone 6+ devices, both devices were instantly recognized. I can deploy and debug to both devices (remembering to change platform specific start up project!) and so could easily demo a POC Xamarin app I wrote. Not bad for preview software!
Good job @JamesMontemagno, good job to you and Xamarin.
