I'm building a new project in MVC, so still kind of new with all the stuff.

Currently I need to loop through a node within the Media Node Tree. Eg NodeId 4378

How do you do this in the new MVC. I've tried to use

var test = UmbracoContext.Current.MediaCache.GetById(4378)

But I can't get anything out of test.Children at all (even though the children exist).

I'm currently using the old way as below:

var test = new DynamicNode(4378);

Any idea how this can be done in MVC?

Any help will be appreciated

Thanks
