    Using IContentService inside a UmbracoDefaultOwinStartup Hangfire scheduler

    Note I are using umbraco 8.12.2.

    I have successfully created a Hangfire scheduler that crawls another website for price information.

    What I need to do now is store that information on the correct doctype page.

    doctype is IBDeCommerce_Product can read these pages and get the old data using

    var umbracoContextFactory = Current.Factory.GetInstance<IUmbracoContextFactory>();
                using (var contextReference = umbracoContextFactory.EnsureUmbracoContext())
                    var umbracoContext = contextReference.UmbracoContext;
                    var content = (IPublishedContent)umbracoContext.Content.GetAtRoot().FirstOrDefault();
    .... navagate the decendents get relivant info as needed 
    ProductPriceUpdate(productUdi, Product.ProductPrice);
            private void ProductPriceUpdate(GuidUdi productUdi, IBDPrice Price)
                IContentService sender = (IContentService)DependencyResolver.Current.GetService<IUmbracoContextFactory>().EnsureUmbracoContext().UmbracoContext;
                IContent content = sender.GetById(productUdi.Guid);
                content.SetValue("ProductPrice", Price);

    I can load the new values into where I need them to go then I call the ProductPriceUpdate method to re publish the content.

    I think Im half way to the answer but I need to access the IConentService correctly as this line is where everything falls over.

            IContentService sender = (IContentService)DependencyResolver.Current.GetService<IUmbracoContextFactory>().EnsureUmbracoContext().UmbracoContext;

    log error as below. Which makes sense but how do I declear a IContentService so it works.

    Use Dependency resolver like this:

    IContentService sender = DependencyResolver.Current.GetService<IContentService>();
