A new Project that I have released today. Before there was only a Highlighter for Notepad++ and here im expanding it to Visual Studio. It is planned to also be funcitonal with Atom Editor and Sublime Text, also planned is a Linter, to see Errors inside a file while editing it.
The current Highlighting does not support Stations, Canals, Bridges, Towns, Houses and Airports.
Have fun coding
