ASP.NET Core module not in IIS

I am keep getting 500.19(0x8007000d) error when running my .NET core project through IIS Express. After a bit digging, it looks like IIS doesn't recognize <aspNetCore> as a valid element in the web.config.

Here are the things I've tried:

• installed URL rewrite module as someone suggested installed
• AspNetCoreModule throgh here: https://www.microsoft.com/net/download/dotnet-core/runtime-2.0.5.
• installed .NET Core Windows Server Hosting bundle.

I've tried adding it as a managed module and put the path for AspNetCoreModule, but looks like it doesn't fix the issue. Enable stdoutLog doesn't work, because it simply won't generate any log file.

Any idea on how to solve this?

I got it working finally. Because all my website is under the default website, I went to install AspNetCoreModule module for the default website.

After it was installed, I noticed a change in the web.config under the default website. At the same time, AspNetCoreModule module is also listed as Native module in the module section.

The real error message is web.config was trying to install AspNetCoreModule, but it is already installed. Then I deleted the <modules> section in the web.config under the default website and it worked...

The website used to work before I turned off/on windows IIS features. Really not sure what caused this...
