How to Install ASP.NET 4.5 in Windows 8

Introduction

In previous versions of Microsoft Windows running Internet Information Services, the "aspnet_regiis -I" command could be used to install the ASP.NET feature. In Windows 8 however, when you try to install ASP.NET 4.5 using "aspnet_reg -I" then this command does not work and instead shows an error indicating that this option is not supported on this version of the operating system.
