title: MVC application throws error when opening dev tools in browser
body: <p>I'm catching an error in my Application_Error method in global.asax when opening the dev tools in my browser.  It's happening in both Chrome and IE (haven't tried any other browsers).  This just started happening.  The error is <strong>"The controller for path '/Scripts/kendo.all.min.js.map' was not found or does not implement IController."</strong>.  </p>
  
  <p>I'm getting the same error for different files.  </p>
  
  <ol>
  <li>The controller for path '/Content/kendo.common.min.css.map' was not found or does not implement IController.</li>
  <li>The controller for path '/Scripts/kendo.all.min.js.map' was not found or does not implement IController.</li>
  <li>The controller for path '/Scripts/kendo.aspnetmvc.min.js.map' was not found or does not implement IController.</li>
  <li>The controller for path '/Scripts/kendo.timezones.min.js.map' was not found or does not implement IController.</li>
  <li>The controller for path '/Content/kendo.common-bootstrap.min.css.map' was not found or does not implement IController.</li>
  </ol>
  
  <p>I'm using Visual Studio 2017 and Kendo v2018.1.117.  No idea why all of a sudden this started happening.  The error is thrown multiple times.  My application launches fine, but when I try to open the dev tools to debug a javascript function from one of m views, it blows up.  It also blows up when I open the dev tools from my Home view - which isn't anything fancy.  Only seems to happen with the Kendo files for some reason.  I've compared this project to another project I'm working on that are very similar and can't find any difference that might point to the cause of this.</p>
  
  <p>Any ideas?  </p>
