问题 I've got a Xamarin Forms solution with iOS and Android projects. The iOS side was working, I switched over and did a bunch of work on the Android side. Now I need to do some more iOS stuff (push notifications) and I can't get the iOS Simulator to kick in. Xcode is installed, VS says it can see the SDK. I can open the simulator from XC but inside VS no matter what Debug combination of the .iOS project I select all I get is "Generic Simulator". Any ideas? 回答1: See the answer in the comment

问题 I'd like to ask anyone out there whether is possible, as of today, to develop a Windows/MacOS cross platform application using WPF (in Visual Studio) and Xamarin.Mac (in Xamarin Studio for Mac). I searched the web, twitted people (Stuart, I know you pointed me to loqu8 build some days ago, but I'm just stuck :P) but nothing really useful came up.
