When I'm using Visual Studio Development Server (http://localhost:64217/application) CSS gets lost and Chrome is showing the following warnings and errors:
Resource interpreted as Stylesheet but transferred with MIME type text/html:
Uncaught SyntaxError: Unexpected token <
When using IIS server (http://localhost/application) the styles are fine.
I've checked these duplicate questions Visual Studio Development Server not updating css and javascript? and Lose “modern” (CSS3) styles when viewing on IIS vs VS Development Server [closed]. Unfortunately none of them helped me.
I've tried clearing the cache and also didn't help. Any guesses what might cause this to happen are very appreciated.
Also I have to mention that this happened today. Back in the past I was using both IIS and Development Server and I didn't have this problem.
EDIT
I'm using Jquery Mobile and I've included the JQM CSS in the master page:
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" runat="server" />
All the other CSS files are included in App_Themes/Default and included in the web.config:
<pages theme="Default" />
