HTTP Error 500.19 - Internal Server Error - HRESULT: 0x8007000d

I added URL rewrite section in web.config file in .Net Core 2.2 Application, and it starts generating the error HTTP Error 500.19 - Internal Server Error.

Error Details:

    Server Error in Application "application name"
    HTTP Error 500.19 – Internal Server Error
    HRESULT: 0x8007000d
    Description of HRESULT
    The requested page cannot be accessed because the related configuration data for the page is invalid.

Cause

As per MSDN:

This problem occurs because the ApplicationHost.config or Web.config file contains a malformed XML element.

Resolution

As per MSDN:

Delete the malformed XML element from the ApplicationHost.config or Web.config file.

But since URL rewrite config section is not malformed as these are all valid config xml. In my case I found that URL rewrite module was not installed on the server, so installing the missing module fixed my issue.

You can download URL Rewrite Extension from Official Microsoft IIS Site:

Or use Direct MSI link for winx64

It should start working at this point.

Install .Net Core Hosting Bundle and reset IIS:

If it still not works, try to install / repair the .Net Core Hosting Bundle. e.g You can download version 6.0 from Download .NET 6.0

Finally, reset IIS by running the following command:

iisreset

You need to open the command prompt with Run as administrator option.
