Cannot enable .Net Extensibility and ASP.NET in Windows Features after VS installations

Question

User1000638852 posted

I have installed VS2003, VS2008, VS2010 and VS2013 on a WIN7 machine. After all the installations I tried to turn on .Net Extensibility and ASP.NET under Windows Features > IIS > World Wide Web Services. I suspect that it has something to do with the builtin web servers in the VS IDEs. Does anyone have a workaround for fixing this issue?

I need those turned on for other projects...

Hi,

Please be always explicit. By "cannot" do you mean that those options are disabled ? This is just those options or can't you enable IIS as well ?

With 2005/2008/2010/2012, I still could. Ah, could it be that .NET Framework 3.5.1 is not checked in the Windows features ? IMHO it is unrelated to VS.

Hi jjmonty,

How did you find that issue? Could you enable it before install the VS?

For that issue, I think maybe there are something errors in your OS. You may update your OS to the latest version and try again.

On the other hand, please try it by using ASP.NET IIS Registration Tool.

# ASP.NET IIS Registration Tool (Aspnet_regiis.exe)

I resolved this on my own (after many scenarios, including uninstalling VS 2013).

In Control Panel > Windows Features, I unchecked the option for "Internet Information Services Hostable Web Core" and clicked OK to essentially uninstall this option.

I opened Control Panel > Windows Features again and re-checked "Internet Information Services Hostable Web Core", then under IIS > WWW Services I checked ".Net Extensibility" and "ASP.Net" then clicked OK. These are the original options that were throwing the error and not installing.

All three installed without errors.

Note, it is unclear if I could have done this before uninstalling VS 2013 to fix this.
