I want to create a cross platform application. For that, I am using Mono.
When I compile my code in Mono, I get an error: vehicleRouteCorePlanner (my dll file) could not found. But I have added that dll into my project.

error in line 2 and 3

It is running fine when I run directly from Visual Studio.
                        
Make the "copy local" property of dll to true before compiling
