Mono aspx error 500: System.Web.Security.FileAuthorizationModule.Init not implemented

Question

I have a CentOS 7 VM installed with all httpd / mysql packages etc. I wanted to run a ticketsystem called SmarterTrack, which is build in ASPX. Looked eveything up and installed the necessary packages I could find on internet (mono server and xsp).

Everything seems to be running fine now (mono server is running etc) but when I go to the website I get an error 500:

System.NotImplementedException
The method or operation is not implemented.

Description: HTTP 500.Error processing request.

Details: Non-web exception. Exception origin (name of application or object): System.Web.
Exception stack trace:
  at System.Web.Security.FileAuthorizationModule.Init (System.Web.HttpApplication app) [0x00000] in /builddir/build/BUILD/mono-4.2.1/mcs/class/System.Web/System.Web.Security/FileAuthorizationModule.cs:51

And in my httpd errorlog I see this:

Listening on: /tmp/mod_mono_server_testing.mydomain.com
Root directory: /var/www/clients/client1/web9/web/
Exception while initOnce: System.NotImplementedException: The method or operation is not implemented.

Please restart your app to unlock it

What could be the issue here?

`The method or operation is not implemented.` Go find a Windows server to run this app. — Michael Hampton, Jan 05 '16 at 18:54
Tried that but the application store keeps crashing when the website is being visited — Cris Kolkman, Jan 05 '16 at 18:57

Unfortunately, Mono doesn't have an implementation for the (System.Web.Security)FileAuthorizationModule. As you can see in the content linked, the class is just there as a stub, so that compilation against it works, but it will not run properly at runtime.

After Microsoft released .NET sources with the MIT license, you could think that Mono could adopt referencesource's sources for this class, however this is currently not possible because this class uses under the hood the UnsafeNativeMethods class, which gives a hint that it uses a non-cross-platform approach (Mono should however remain compatible with non-Windows platforms).
