title: How to access a class which is in a folder c# (wpf)?
body: <p>I'm building a WPF application. I'm almost finished with one part of it, and now I want to clean up the code a bit. English is not my native language (so sorry if this gets marked as a duplicate) and I couldn't find anything about this, so I hope someone can help me out.</p>
  
  <p>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 its functions?</p>
