iis - ERROR 404.3 Not Found for JSON file

Question

I have been getting the "ERROR 404.3 Not Found" for JSON file that I am calling using AJAX call on "Internet Information Services 7.5" even after I have activated all the "Application Development Features". Other than JSON file, all other files are getting loaded.

I am running an HTML page on IIS server on my local machine.

If I open the file directly then there is no problem at all. When I host the files on an online server it works fine.

Any quick help will be much appreciated.

As suggested by @ancajic i put the below code after connectionString tag in my web.config file and it worked.

  <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".json" mimeType="application/json" />
    </staticContent>
  </system.webServer>
