I have downloaded the Events Console app from this link https://osdn.net/projects/sfnet_onvifdm/downloads/console_net4_0/EventsConsole.zip which works perfectly fine in windows OS. But my requirement is to run a similar kind of app in Linux Ubuntu 18.04. I have installed Mono runtime for this to work from this link https://www.mono-project.com/download/stable/#download-lin, but I am getting a runtime exception. I tried updating the DLL's and different versions of mono still the issue is not resolved.
