Finally I managed it to work. For those, who are searching for a similar solution:

In my Apache vHost Configuration I need to add

MonoSetEnv inventur.netdienste.com MONO_IOMAP=all

That directive translated the forward slashes to backward slashes.

This also fixed the issue for me when running from MonoDevelop. Launching it as `MONO_IOMAP=all monodevelop` worked. – Scott Weldon Jul 18 '16 at 00:12

I'm working on OS Sierra and just only have installed VS. Where should I put this line? Could you explain? Thanks! – Icet Dec 10 '16 at 22:48

I do not know if this is what's causing your problem but you have some incorrectly facing slants in your path string.

It is either:

"/srv/www/proj/bin/roslyn/csc.exe"

Or:

"\srv\www\proj\bin\roslyn\csc.exe"

Where can I change this path setting? I didn't find it, – Daniel Pomrehn Jan 14 '16 at 04:29
@DanielPomrehn I just assumed you had a string incorrectly typed in your source code somewhere, although the exception is not helping tell where. – MiddaPhofidda Jan 14 '16 at 15:26
