[Freeswitch-users] mod_managed: Failed to create shadow copy

[Shane Mitchell]

Hi everyone,

I'm after a bit of mod_managed help from those with experience.

To explore how we can use mod_managed, I'm trying to simply get it up-and-running. To test, I'm trying to run Demo.csx (from source), however an ExecutionEngineException (see below) is always thrown whenever trying to load the csx file.
 
I'm using latest stable Debian Jessie and FreeSWITCH (from packages).  While I've been programming in C# since 1.0, I've never used mono, so I simply installed mono-complete from packages.  I have also tested mono (and FreeSWITCH) successfully.  I have researched related errors online with no luck or inspiration for a solution.

Does anyone know why I would get this problem? Do I need to create any symlinks, install any packages, create directories (other than conf/mod/managed), etc to get mod_managed to work on a new install?

Thanks all, much appreciated.
