C# 6 and .NET Core 1.0: Modern Cross-Platform Development

Overview of this book

With the release of .NET Core 1.0, you can now create applications for Mac OS X and Linux, as well as Windows, using the development tools you know and love. C# 6 and .NET Core 1.0 has been divided into three high-impact sections to help start putting these new features to work. First, we'll run you through the basics of C#, as well as object-orient programming, before taking a quick tour through the latest features of C# 6 such as string interpolation for easier variable value output, exception filtering, and how to perform static class imports. We'll also cover both the full-feature, mature .NET Framework and the new, cross-platform .NET Core. After quickly taking you through C# and how .NET works, we'll dive into the internals of the .NET class libraries, covering topics such as performance, monitoring, debugging, internationalization, serialization, and encryption. We'll look at Entity Framework Core 1.0 and how to develop Code-First entity data models, as well as how to use LINQ to query and manipulate that data. The final section will demonstrate the major types of applications that you can build and deploy cross-device and cross-platform. In this section, we'll cover Universal Windows Platform (UWP) apps, web applications, and web services. Lastly, we'll help you build a complete application that can be hosted on all of today's most popular platforms, including Linux and Docker. By the end of the book, you'll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET Core.

ASP.NET Core controllers


Now that MVC knows the names of the controller and action, it will look for a class that implements an interface named IController. To simplify the requirements, Microsoft supplies a class named Controller that your classes can inherit from.

The responsibilities of a controller are as follows:

  • To extract parameters from the HTTP request

  • To use the parameters to fetch the correct model and pass it to the correct view

  • To return the results from the view to the client as an HTTP response

Defining the Home controller's actions

In the Solution Explorer window, expand the Controllers folder and double-click on the file named HomeController.cs:

public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
    public IActionResult About()
    {
        ViewData["Message"] = "Your application description page.";
        return View();
    }
    public IActionResult Contact()
    {
        ViewData["Message"] = "Your contact page...
