Dependency Injection in Views

ASP.NET MVC -> Views -> Dependency Injection in Views

[ardalis]

@danroth27 Do you want me to expand on what's already here: https://github.com/aspnet/Docs/blob/master/mvc/views/dependency-injection.rst

[danroth27]

@rynowak @Eilon @NTaylorMullen Does this article need more detail or should we just leave it as is?

[NTaylorMullen]

Hmm, i'm not sure this warrants an entire article.

[Eilon]

The doc doesn't really say why you'd want to do this. Are we trying to have some conceptual content in here?

BTW this will eat at me forever unless I say something: there are spaces missing after some of the colons in the code:

          <li>Items: @await Statistics.GetCount()</li>
          <li>Completed:@await Statistics.GetCompletedCount()</li>
          <li>Average Priority:@await Statistics.GetAveragePriority()</li>

In the community stand up it was stated that the purpose of dependency injection in views is to have the controller not need to know about view specific services.

[ardalis]

@danroth27 should I write something up that includes some conceptual background and answers @Eilon 's why question?

[danroth27]

@ardalis Sounds good - one example use case is the view localizer service.

[ardalis]

@danroth27 it looks like this sample is post-RC1;
https://github.com/aspnet/Mvc/blob/dev/samples/LocalizationSample.Web/Startup.cs
(it doesn't exist in RC1 tag and the DefaultRequestCulture doesn't exist in RC1)
should I hold off on updating this until RC2 drops?

[danroth27]

@ardalis No, let's not wait. We can either refer to the correct APIs in RC1, or just remove the localization content from this article for now.
