Studying MVVM. After going through several toolkits, I stopped at SimpleMVVM

He himself seems to have figured out the toolkit itself, but the question arose. There is an application - it scans files of a specific type in a given directory, reads a description from each one and creates the corresponding xml file. Then from this xml-file is a selection of the necessary parameters and displayed on the screen. At the moment, scanning the catalog is done in the form of a static class with two methods:

public static class Scaner { public static int NewScan() {...}; public static int Rescan() {...}; }

In the future we plan to create another similar static class - a converter from one format to another.

The question is: where should these two classes be located if they do not belong to Models or ViewModels (at least as far as I understand it), and how can they be correctly called?

    If the project is small, you can place this class next to the class (s) where it is used. If the project is large, then, as a rule, it is divided into parts according to the area (for example, UI , TextProcessing , ImageProcessing , etc.), so you can put it in a separate subproject ( Scanning ).
