Hey Rony,
It sounds like you need to add the namespace which encapsulates the Path class before you can add it to the app. In Visual Studio or VS Code, you should be able to automatically resolve the namespace by left-clicking the Path text, pressing CTRL., and selecting Using System.IO

Otherwise, add it at the top of the file with all the other using statements.
