ASP.NET MVC 6 View Injection using Inject

ASP.NET MVC 6 View Injection using Inject

Earlier I mentioned ASP.NET MVC 6 Dependency Injection using a simple container that is bundled with ASP.NET MVC 6. This is great for injecting dependencies into controllers, filters, etc. In this tutorial I mention the new inject keyword that can be added to razor views for injecting dependencies into views.

Registering Services

First, we have to register the service with the IoC container built into ASP.NET MVC 6.

public void ConfigureServices(IServiceCollection services) {
    ...
    services.AddTransient<ITestService, TestService>();
}

This is no different from the previous example: ASP.NET MVC 6 Dependency Injection.

Inject Keyword for Razor Views

Next we can inject the the service for use in the razor view using the new inject keyword.

@inject ITestService testService

Now the service is available to our view and can be used appropriately anywhere in the view.

@using Sample.Services
@inject ITestService testService
<p>So I looked down and said... @testService.WhatAreThose()</p>

Conclusion

Injecting dependencies in ASP.NET MVC 6 views using the new inject keyword can make things quite a bit easier. Now that ASP.NET MVC 6 has a basic IoC container we'll probably see more people start to use dependency injection not only in their views, but also in their controllers, filters, services, etc.
