ASP.NET State Service for Windows 8

ASP.NET State Service is not installed by default in Windows 8 and should not be installed on a “home” system.
To enabled this navigate to Control Panel -> Programs -> Programs and Features ->  Turn Windows Features on or off. Select “ASP.NET 4.5″

Open Run (Win + R) and write “services.msc”

Here right click on “ASP.NET State Service” and press start.
