I'm not sure if this is useful or not, but there is a FileSystemsTests class within the V8 source code here, which should hopefully point you in the right direction.

As a quick reference, the line:

var fileSystem = _factory.GetInstance<IMediaFileSystem>();

Seems to be the equivalent of the V7:

var fs = FileSystemProviderManager.Current.GetFileSystemProvider<MediaFileSystem>();

Hi Rhys,

I've not tested the code yet, but your reply has been super helpful - hopefully it'll work.

I'll confirm whether correct once tested.

Thanks amigo.

Hi Philip Did you find any solution? :)

I had to stop working on this project, so I don't have an answer yet. But I'll post an update if / when I get time to resume my work. Sorry I can't be of more assistance /facepalm

Hi Philip,

There is a few different ways to access the media file system.

1. Use the static Current class (it's located in the Umbraco.Core.Composing namespace). With this, your code would look something like:

IMediaFileSystem media = Current.MediaFileSystem;

2. Use dependency injection. Whenever possible, this is the preferred way to access most services and resources in Umbraco 8.

For instance if you have a WebAPI controller, you can add the needed interfaces in the constructor of your controller, and dependency injection will do it's magic:

public class MyController : UmbracoAuthorizedApiController {

    private readonly IUmbracoSettingsSection _umbraco;

    private readonly IMediaFileSystem _media;

    public MyController(IUmbracoSettingsSection umbraco, IMediaFileSystem media) {
        _umbraco = umbraco;
        _media = media;
    }

    [HttpGet]
    public object MyMethod() {
        return new {
            umbraco = _umbraco?.GetType() + "",
            media = _media?.GetType() + ""
        };
    }

}

is working on a reply...
