Getting Error While Deploying WEB API to IIS 10.0

Question

Hello everyone,

 

I'm facing an issue regarding deploying WEB API to IIS. Everything works well whenever I run my project on localhost. The error I'm facing is :

 

HTTP ERROR 500.19 - INTERNAL SERVER ERROR

 

The requested page cannot be accessed because the related configuration data for the page is invalid

 

I've tried many things but nothing worked for me.

 

OS: Windows 10

IIS Version 10.0

Visual Studio Version 2015

 

This is how my web config looks likes

 

<?xml version="1.0" encoding="utf-8"?>
