ASP.NET 4.5 has not been registered on the Web server

asp.net-mvc-4, iis-7.5, localdb, sql-server-express

Solution

Maybe you have to execute the following in the Visual Studio Tools command prompt:

aspnet_regiis -i

You can read more about the ASP.NET IIS Registration Tool (Aspnet_regiis.exe) here.

Problem

In my Win 7 development machine, and in order to use SQL Express instance instead of the localDB installed by default. I unchecked "Use IIS Express" in my MVC 4 project properties page (Web tab), then I got the following error: ASP.NET 4.5 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.5 in order for your site to run correctly. I verified that ASP.NET is activated within the IIS features. Please what could be done to resolve this?
