I know i can use EditorUtility.saveFilePanel from the editor, but I get an error when I try to build if I attempt to include UnityEditor so I can use this in my application. That function is exactly the functionality I want, how can I achieve that without using EditorUtility functions?

Create your own native plugin (DLL) or use one available on asset store
