I'm having an issue in IIS 7.5 where the ASP.NET feature section isn't showing on my web application.
My environment: Windows 2008 R2 SP1, IIS 7.5 (7.5.7600), .NET Framework 4.0
My issue is similar to the issue posted here: No asp.net features on IIS 7.5, only my environment is different. The 'add features' fix mentioned in that post doesn't appear to work in Windows Server 2008, as I'm not seeing a simple "ASP.NET" feature that can be selected.
I tried running the aspnet_regiis tool as administrator against .NET 4.0 with no luck. The application pool selected for the web application is currently configured to use .NET 4.0. This application is functional, so I'm assuming that .NET 4.0 is installed correctly, but I'd like to be able to configure a few more things that are in the ASP.NET section.
Try Roles > Right Click Web Server (IIS) > Add Role Services > Application Development to turn on the ASP.Net features in IIS
