I made a MVC4 application with .net 4.5 using razor engine. It works fine when run locally with visual studio.
When I deploy to IIS on windows server 2008 R2(all windows updates done), it appears my bundles do not work and the CCS is not loading. I tried viewing the site on the server, viewed source went to the bundle link for the css, and it loads some css and then there is an IIS error of:
HTTP Error 403.14 – Forbidden The Web server is configured to not
list the contents of this directory.
What I have tried:
1) Ensured .net 4.5 is installed.
2) Added <modules runAllManagedModulesForAllRequests="true"/> to my web.config
3) Ran %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir in cmd
4) Checked that my app pool was set to Integrated Mode
5) Checked that it’s set to use .net 4
You’ll find your answer here: ASP.NET MVC framework 4.5 CSS bundles does not work on the hosting
The short answer is to make sure that your bundle names don’t conflict with the names of paths in your sites.
