Hi Peter

There is some examples her of accessing the UmbracoContext and ContentCache from non Http Request places:

https://our.umbraco.com/Documentation/Implementation/Services/

I know NodeFactory and DynamicNode have beem removed in Umbraco 8

IPublishedContent and UmbracoHelper would be the equivalents.

And I think you'd need to use IUmbracoContextFactory + EnsureUmbracoContext(), to get access to the ContentCache

Hi Marc, I thought i'd post up my findings so far on this: I created a SiteSearch.cs file with the following:

namespace Umbraco8.Utils.Services
{
     public class SiteService : ISiteService
    {
      private readonly IUmbracoContextFactory _umbracoContextFactory;
      public SiteService(IUmbracoContextFactory umbracoContextFactory)
       {
          _umbracoContextFactory = umbracoContextFactory;
       }

public IPublishedContent GetContentUsingAlias(string alias)
{
  IPublishedContent content = null;
  using (UmbracoContextReference umbracoContextReference = _umbracoContextFactory.EnsureUmbracoContext())
  {
    IPublishedContentCache contentCache = umbracoContextReference.UmbracoContext.Content;
    IPublishedContent siteRoot = contentCache.GetAtRoot().FirstOrDefault();
    content = siteRoot?.FirstChild(f => f.ContentType.Alias == alias) ?? null;
  }
  return content;
}

public IPublishedContent GetContentUsingAlias_DescendantsOrSelf(string alias)
{
  IEnumerable<IPublishedContent> contentList = null;
  IPublishedContent content = null;
  using (UmbracoContextReference umbracoContextReference = _umbracoContextFactory.EnsureUmbracoContext())
  {
    IPublishedContentCache contentCache = umbracoContextReference.UmbracoContext.Content;
    IPublishedContent siteRoot = contentCache.GetAtRoot().FirstOrDefault();
    contentList = siteRoot?.DescendantsOrSelf().Where(f => f.ContentType.Alias == alias);
    content = contentList.ElementAt(0);
  }
  return content;
}

public IPublishedContent GetContentUsingAliasTest(string alias)
{
  IPublishedContent content = null;
  IPublishedContent content2 = null;
  IEnumerable <IPublishedContent> content3 = null;
  using (UmbracoContextReference umbracoContextReference = _umbracoContextFactory.EnsureUmbracoContext())
  {
    IPublishedContentCache contentCache = umbracoContextReference.UmbracoContext.Content;
    IPublishedContent siteRoot = contentCache.GetAtRoot().FirstOrDefault();
    content3 = siteRoot?.DescendantsOrSelf().Where(f => f.ContentType.Alias == alias);
    content2 = content?.FirstChild(f => f.ContentType.Alias == "websiteNavigationSettings") ?? null;
  }
  return content2;
}

public IPublishedContent GetContentUsingId(Int32 id)
{
  IPublishedContent content = null;
  using (UmbracoContextReference umbracoContextReference = _umbracoContextFactory.EnsureUmbracoContext())
  {
    IPublishedContentCache contentCache = umbracoContextReference.UmbracoContext.Content;
    IPublishedContent siteRoot = contentCache.GetAtRoot().FirstOrDefault();
    content = siteRoot?.FirstChild(f => f.ContentType.Id == id) ?? null;
  }
  return content;
}

} }

Then I created the Interface, ISiteService.cs:

using System;

using System.Collections.Generic; using Umbraco.Core.Models.PublishedContent;

namespace Umbraco8.Utils.Services { public interface ISiteService { IPublishedContent GetContentUsingAlias(string templateAlias); IPublishedContent GetContentUsingAlias_DescendantsOrSelf(string templateAlias); IPublishedContent GetContentUsingAliasTest(string templateAlias); IPublishedContent GetContentUsingId(Int32 id); } }

To use this in SurfaceControllers:

Using Umbraco8.Utils.Services;

using Umbraco.Core.Configuration; using Umbraco.Web; using Umbraco.Core.Services; using Umbraco.Core.Cache; using Umbraco.Core.Logging; using Umbraco.Core.Models.PublishedContent; using System.Web.Mvc;

namespace Umbraco8.SurfaceControllers { public class CookieController : SurfaceController {

private readonly ISiteService _siteService;

public CookieController(ISiteService siteService)
{
  _siteService = siteService ?? throw new ArgumentNullException(nameof(siteService));
}

To use this in a view or partial view:

@inherits Umbraco.Web.Mvc.UmbracoViewPage

@using Newtonsoft.Json; @using CommercialTrust.Utils.Services @using Current = Umbraco.Web.Composing.Current;

@{ ISiteService SiteService = Current.Factory.GetInstance

I have also found that i can also use this in a class file, such as a helper:

using Umbraco8.Utils.Services;
using System;
using System.Collections.Generic;
using Umbraco.Core.Models.PublishedContent;

namespace Umbraco8.Utils
{
   public class Helper
   {
       private readonly ISiteService _siteService;

       public Helper(ISiteService siteService)
       {
         _siteService = siteService ?? throw new ArgumentNullException(nameof(siteService));
        }
public void IterateRecentNewsChildren(IPublishedContent parent, List<string> IgnoreAliasList, List<string> ignoreNodeList, List<string> nodeList)
{
  foreach (var item in parent.Children)
  {
    IPublishedContent nextParent = _siteService.GetContentUsingId(item.Id);
    if (!IgnoreAliasList.Contains(item.ContentType.Alias) && !ignoreNodeList.Contains(item.Id.ToString()) && nextParent.GetProperty("umbracoNaviHide").GetValue().ToString() != "1")
    {
      nodeList.Add(item.Id.ToString());

    }
    if (!ignoreNodeList.Contains(item.Id.ToString()))
    {
      IterateRecentNewsChildren(nextParent, IgnoreAliasList, ignoreNodeList, nodeList);
    }
  }
}
   }
}

is working on a reply...
