Xamarin doesn't support older versions of VS anymore. Xamarin不再支持VS的旧版本。 The recommendation is to use Visual Studio 2015 or 2017 currently: 建议当前使用Visual Studio 2015或2017：
Xamarin for Visual Studio supports any Visual Studio 2015 or 2017 (Community, Professional, and Enterprise) and non-Express editions of Visual Studio 2013 Update 2.
