Hi Oumarou

For neatness, and if you are using a service in lots of different views then you could create your own version of UmbracoViewPage... and wire things up once...

There is some WIP documentation in progress here:

https://github.com/umbraco/UmbracoDocs/compare/v8/ServicesPattern?short_path=cf2726d#diff-cf2726d2ea2b6f60e0225ce051876a55

that has the following example of how to do this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Umbraco.Core;
using Umbraco.Core.Cache;
using Umbraco.Core.Composing;
using Umbraco.Core.Services;
using Umbraco.Web.Mvc;
using Umbraco8.Services;
using Current = Umbraco.Web.Composing.Current;

namespace Umbraco8.ViewPages
{
    public abstract class CustomViewPage<T> : UmbracoViewPage<T>
    {
        public readonly ISiteService SiteService;
        public CustomViewPage() : this(
            Current.Factory.GetInstance<ISiteService>(), 
            Current.Factory.GetInstance<ServiceContext>(),
            Current.Factory.GetInstance<AppCaches>()
            )
        {
        }
        public CustomViewPage(ISiteService siteService, ServiceContext services, AppCaches appCaches)
        {
            SiteService = siteService;
            Services = services;
            AppCaches = appCaches;
        }

        protected override void InitializePage()
        {
            base.InitializePage();
        }
    }
    public abstract class CustomViewPage : UmbracoViewPage
    {
        public readonly ISiteService _siteService;
        public CustomViewPage() : this(
            Current.Factory.GetInstance<ISiteService>(),
            Current.Factory.GetInstance<ServiceContext>(),
            Current.Factory.GetInstance<AppCaches>()
            )
        { }

            public CustomViewPage(ISiteService siteService, ServiceContext services, AppCaches appCaches)
        {
            _siteService = siteService;
            Services = services;
            AppCaches = appCaches;
        }

        protected override void InitializePage()
        {
            base.InitializePage();
        }
    }
}

and then in your view

@using Umbraco8.ViewPages
@inherits CustomViewPage
@{

    Layout = "master.cshtml";
    IPublishedContent newsSection = SiteService.GetNewsSection();
}
<section class="section">
    <div class="container">
        <article>

Anyway it's just a thought... the key to it is anywhere you can get the current reference from a service that's registered with DI by using:

using Current = Umbraco.Web.Composing.Current;
 Current.Factory.GetInstance<ISiteService>()

if that helps
