When I run my ASP.NET MVC 4 website on my Fedora 20 workstation with xsp4 (from MonoDevelop or directly) I'm getting the following exception:

System.Web.HttpRuntime.FinishWithException (wr={Mono.WebServer.XSPWorkerRequest}, e={System.Web.HttpException:  ---> System.Web.HttpException: The pre-application start initialization method Start on type System.Web.WebPages.PreApplicationStartCode threw an exception with the following error message: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: An exception was thrown by the type initializer for <Module> ---> System.Security.SecurityException: No access to the given key ---> System.UnauthorizedAccessException: Access to the path "/etc/mono/registry" is denied.

I've checked it and there is no registry file or folder in /etc/mono/. I also can't find it in any subfolder, how can I resolve this question?

I'm running Fedora 20 with the latest 3.15.6 kernel

I have another setup in Ubuntu 14.04 LTS and that one works, so it might be something with the mono version, or maybe I'm missing some library?

Turns out simply creating the folder using mkdir

sudo mkdir /etc/mono/registry

and setting the right permissions using chmod

sudo chmod uog+rw /etc/mono/registry

does the trick.

However I still don't understand where such a folder is hidden in Ubuntu and why it doesn't need to be created there, as well as why it isn't created automatically during the installation.
