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);
            sender.SaveAndPublish(content);
        }

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.
