[ubuntu] Unable to run .net app with Mono - mscorlib.dll not found (version mismatch?)
If you just want to run it,
sudo apt-get install libmono2.0-cil libmono-system-net2.0-cil mono-runtime may suffice.
I have a simple .net command line tool written and compiled under Windows, using .net 3.5SP1. I would like to run it on Linux using Mono.
I am using Ubuntu 12.04, and installed Mono Runtime using the Ubuntu software center. If I try to start my app in the terminal by doing:
I get the error:
The assembly mscorlib.dll was not found or could not be loaded. It should have been installed in the 'usr/lib/mono/2.0/mscorlib.dll'.
If I navigate to that location, I see that it does not exist. However, there is
usr/lib/mono/4.0/mscorlib.dll (and some more DLLs in the same folder).
So seemingly there is a version mismatch.
[in case it matters,
mono -V shows
Mono JIT compiler version 18.104.22.168 (Debia 22.214.171.124-1ubuntu2) ]
the package you're looking for was "libmono-system.data2.0-cil" which is installed with Mono-complete
