Consider API Adjustment to Use Interfaces Rather Than Abstract Classes

[Mike-E-angelo]

Cool project. :) Thank you for keeping it current.

Checking this out just now. It appears there are files such as DirectoryInfoBase and FileInfoBase. Has there been any thought towards making these interfaces instead, So IDirectoryInfo and IFileInfo? That way we're really abstracting the goodness and don't have to pass implementations around.

Thank you for any consideration!

Just found a link to this project, looked at the code and saw the same thing and thought the same thing.

This could be a really good project, but it's difficult to take it seriously when it uses abstract classes and inheritance, rather than interfaces. I'm happy to fix and do a PR if you'd like?

I looked at some classes, and mostly the abstract classes are unnecessary.
Introducing interfaces should be straight forward.
