Enable .Net Framework 3.5 Feature in Windows 8

Introduction

 
Windows 8 displays the message "An app on your PC needs the following Windows feature" ".Net Framework 3.5 (Includes 3.0 and 2.0)". This message is displayed when you try to install an application that requires .Net 3.5 but doesn't find this .Net version on your computer.
 
This problem occurs because .Net 3.5 is not automatically installed with Windows 8; only .Net 4.5 Advanced Feature is automatically installed with Windows 8. To remove this problem you have to enable this feature. There are two ways to enable this feature; the first is, when you are online, download and install it and the second is offline using the DISM command in a command prompt window.
