Remote Simulator to Windows option doesn't exist How can get Remote Simulator to Windows when it doesn't exist?

From Introduction to Xamarin.iOS for Visual Studio


  Xamarin for Windows allows iOS applications to be written and tested
  within Visual Studio, with a networked Mac providing the build and
  deployment service.
  
  There are a number of configuration options available, so you can
  decide which works best for your development needs. These are listed
  below:
  
  
  Use a Mac as your main development Machine and run a Windows Virtual
  Machine with Visual Studio installed. We recommend using VM software
  such as Parallels or VMWare .   
  Use a Mac just as a Build Host. In this
  scenario it would be simply connected to the same network as a Windows
  machine with the necessary tools installed. 
  
  
  In either case, you should
  follow these steps:
  
  
  Install the Xamarin.iOS tools on your Mac host and activate your license  
  Configure your Mac  
  Install Xamarin tools on Windows 
  
  
  To develop
  with Xamarin in Visual Studio, you must be using at least Visual
  Studio 2012 Professional or higher. Xamarin will not work with Express
  Editions of Visual Studio, as they do not support add-ins.
