Hi Bo

The UmbracoHelper is made up of multiple bits and pieces - so when you are using it to query content, your actually using the implementation of IPublishedContentQuery... and with the MemberHasAccess method you are actually using the MembershipHelper class...

So it may be as simple as injecting the MembershipHelper into your custom service...

eg

public class MyService : IMyService
{
    public IUmbracoContextFactory Context { get; }
    private readonly MembershipHelper _membershipHelper ;
    public MyService(IUmbracoContextFactory context, MembershipHelper membershipHelper)
    {
        Context = context;
        _membershipHelper = membershipHelper;
    }

    public IPublishedContent TypedContent(int id)
    {
        using (var cref = Context.EnsureUmbracoContext())
        {
            var cache = cref.UmbracoContext.Content;
            var node = cache.GetById(id);
            return node;
        }
    }

    public bool MemberHasAccess(string path)
    {
        // this is I think how
return _membershipHelper.MemberHasAccess(path);
    }
}

However this is a bit of a guess, as I'm not sure if the MembershipHelper relies on there being an UmbracoContext or not when it is injected, if it does this will all work fine if your custom service is only used in Controllers or Views where there is always an UmbracoContext but if you called it from a background thread, it may trigger a boot error...
