To walk through this book and successfully compile all the source code, we require a personal computer that runs Microsoft Windows 10 (or higher) with Visual Studio Community 2015 Update 3 installed for the running of code in chapters 1-8, 10, 11 and Visual Studio Community 2017 RC (Release Candidate) installed for the running of code in chapter 9. We also need the .NET Framework 4.6.2 unless you need to recode all the source code to run in your current version of .NET Framework. You also need .NET Core 1.0 if you want to compile all code in another platform since all code are compatible with .NET Core 1.0.
