How to acces a class which is in a folder c# (wpf) : I'm building a WPF application. I'm almost finished with one part of it, and now I wanna clean up the code a bit. English is not my native language (so sorry if this gets marked ass a duplicate) and I couldn't find anything about this, so I hope someone can help me out.

If i have public voids in a class called 'class.cs' and this class is in a folder called 'classes', how do I access the class so I can use it's functions?
