Team, Do we have final confirmed new method which works with Umbraco 7.5.10? EnsureContext is deprecated. So, if we have any other option to generate UmbracoContext?
Author
EnsureContext is not deprecated, not when looking at the source at least -> https://github.com/umbraco/Umbraco-CMS/blob/release-7.5.11/src/Umbraco.Web/UmbracoContext.cs#L113
If anyone needs help on this, come find us in the unofficial Slack channel -> umbracians.slack.com #help
Hi @Shazwazza,
Is is OK to have set up like this using Autofac:
builder.Register(c => UmbracoContext.Current).InstancePerRequest();
builder.Register(x => new UmbracoHelper(UmbracoContext.Current)).InstancePerRequest();
Thanks!

Hi Guys,
I'm really struggling with this to. Its all new so i haven't got a great understanding sorry.
I have a custom class where I am trying to use the UmbracoHelper.TypedContentAtRoot() to dynamically get the root node but the UmbracoContext.Current is always null and therefore it returns nothing. I have tried using the code above suggested by @YodasMyDad but it doesn't seem to work
if (UmbracoContext.Current == null) { var dummyHttpContext = new HttpContextWrapper(new HttpContext(new SimpleWorkerRequest("blah.aspx", "", new StringWriter()))); UmbracoContext.EnsureContext( dummyHttpContext, ApplicationContext.Current, new WebSecurity(dummyHttpContext, ApplicationContext.Current), UmbracoConfig.For.UmbracoSettings(), UrlProviderResolver.Current.Providers, false); }If i use the following it seems to work. However, through my lack of understanding and resharpher warning me that EnsureContext is obsolete it concerns me of the potential impact.
var dummyContext = HttpContext.Current = new HttpContext(new HttpRequest(null, "https://www.google.com", null), new HttpResponse(null)); UmbracoContext.EnsureContext(new HttpContextWrapper(dummyContext), ApplicationContext.Current);Reading here https://our.umbraco.org/forum/extending-umbraco-and-using-the-api/76889-background-process-value-cannot-be-nullparameter-name-httpcontext i can see that its a bug in 7.4.3. I am using 7.5.3 assembly: 1.0.6092.24019. I have also raised this in OUR https://our.umbraco.org/forum/extending-umbraco-and-using-the-api//81341-contentservice-not-creating-content. This will show you my code and what im trying to do. In short i am trying to do the following in a custom class
Can some one please help?
Thanks
Paul
