解决方法
This option is not supported on this version of the operating system. Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the “Turn Windows Features On/Off” dialog,the Server Manager management tool,or the dism.exe command line tool.
原因是在这个链接：http://support.microsoft.com/kb/2736284.
对我有用的解决方案是在这个链接上发布的,在Neha的答复：System.ServiceModel.Activation.HttpModule error
Everywhere the problem to this solution was mentioned as re-registering aspNet by using aspnet_regiis.exe. But this did not work for me.
Though this is a valid solution (as explained beautifully here)
but it did not work with Windows 8.
For Windows 8 you need to Windows features and enable everything under “.Net Framework 3.5” and “.Net Framework 4.5 Advanced Services”.
Thanks Neha
