Visual Studio 2015 includes a number of options features as a secondary dialog in the installation process. After hitting the Next button shown in Figure 2.1, the installer will launch a secondary selection for optional features. Many of these features are shown in Figure 2.2. Notice these include many optional items required for doing cross-platform mobile development such as Xamarin or the Android SDK and emulator. Most cross platform mobile developers (using Xamarin or Cordova) will want to install these optional items.
