Dependency injection

View classes (RazorPage<T>) support services being injected in their constructors, as illustrated in the following code snippet:

public class MyPage : RazorPage<dynamic>
{
    public MyPage(IMyService svc)
    {
        //constructor injection
    }
}

Views also support having services injected into them. Just declare an @inject element in the .cshtml file with the service type to retrieve and the local variable to hold it, probably at the beginning of the view, like this:

@inject IHelloService Service

After this, you can use the injected Service variable, like this:

@Service.SayHello()

There may be the need to either fully qualify the type name or add a @using declaration for its namespace.

Let's see now how to have our application respond in different languages.
