Missing package "System.Net.Ping"

See original GitHub issue

Our application uses Avalonia but it seems that it’s missing some packages on some installations.

Most of our installations work fine but some have that exception:

Description: The process was terminated due to an unhandled exception. Exception Info: System.IO.FileNotFoundException: Could not load file or assembly ‘System.Net.Ping, Version=4.1.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.
