ASP.NET Core module not in IIS

Question

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

Answer 1

Repairing the core server hosting from the add remove program did the trick - It seems like IIS was installed or changed after core windows server hosting. According to Microsoft is such case you need to repair the hosting bundle

Answer 2

Add Native module with path C:\Windows\system32\inetsrv\aspnetcore.dll

Answer 3

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...
