Running the Installer
Playtime! To write code on the .NET Framework 4.5, let’s start by installing the Full .NET Framework package. That’s really all you need to get started with managed code development.
Where to get it? Browse to http://msdn.com/netframework and click the link to the .NET Framework 4.5 download. The installer itself should be straightforward to run: Accept the license agreement, get a cup of coffee, and you’re ready to go. On Windows 8, you can use the Turn Windows Features On or Off Control Panel applet to enable or disable the .NET Framework 4.5 feature. Figure 3.4 shows the default feature selection on a clean Windows 8 installation.
