Hello !
I just deployed (per copy!) an application from one debian server
to another and tried to execute it:
>
Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly
'System.Core, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' or one of its dependencies.
File name: 'System.Core, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089'

The app was previously compiled on windows and copied over to several
debian servers where ether the packet "mono-runtime" or "mono-complete"
is installed.
Now recompiled the program on linux/debian, having mono 4.2.4 (and
development
tools installed), without changing the problem.
GAC of dev-box:
System.Core, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089
GAC of problem-box:
root@hel:/ops/tools# apt-cache policy mono-runtime
mono-runtime:
Installed: 4.4.1.0-0xamarin1
Candidate: 4.4.1.0-0xamarin1
but NO "System.Core" in gac.
This is on debian/jessie (8.5, kernel 3.16.0), with
mono installed via instructions on the mon website.
The state of the installation result, after installing
mono-runtime:
root@hel:/ops/tools# dpkg -l *mono*

But, sad to say, this is not the end of the story. I took a new box
and first installed "mono-runtime" and the problem persists. Then
I removed the "mono-runtime" and now, I am unable to install something
from mono, wether "-complete" nor "-devel" succeed with a long list
of unresolved dependecies:
root@lila:/ops/install# apt-get install -t wheezy mono-devel

OR:

The following packages have unmet dependencies:

So, I am working two day, just to make a working program running!!!!!
It looks like, I have to re-install the whole computers ????????????????
>From the apt-policy-output you'll see, that a have to specify
"-t wheezy
Hope, someone can shed some light onto this. It is not possible
to install the dev-env on every box. BTW, a search in the internet
offers countless of errors of this type! Installing from debian stable
works painless. Probably the mono repository should be declared
as "highly experimental" ???
Thanks,
Manfred
