HttpCompileException: “External exception” when trying to access razor view in ServiceStack hosted on Apache+mod_mono

问题

I am getting HttpCompileException when trying to access a razor view. Error log contains no information. The same deployment works on NGinx+FastCGI, but not on Apache+mod_mono.

I am not using the mod_mono AutoConfiguration because I have not (yet) found a way how to make it work.

This is my "manual" apache2.conf configuration for mono:

MonoAutoApplication disabled
AddHandler mono .aspx .ascx .asax .ashx .config .cs .asmx .axd
MonoApplications "/:/var/www/MyAppName"
<Location />
    SetHandler mono
</Location>

This is the error I am getting when trying to access a razor view:

System.Web.HttpCompileException: External exception

I have looked as RazorPageHost.Compile in ServiceStack sources and I can see that HttpCompileException is thrown in case result from _codeDomProvider.CompileAssemblyFromDom contains some Errors, which makes sense.

Is there some special configuration to make CodeDomProvider work on mod_mono Apache-hosted ServiceStack applications?

EDIT: It looks like this is not specific to ServiceStack, other ASP.NET apps deployed to the same server have the same issue.
