C# 6 and .NET Core 1.0

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.

Building cross-platform web applications using ASP.NET Core


Now, let's make a simple ASP.NET Core web application.

Creating the simplest ASP.NET Core web application

You will enter some commands in the Terminal prompt to:

  • Create a new directory named HelloWeb and move into it

  • Create two files named startup.cs and project.json

  • Start Visual Studio Code so that we can edit the files in an IDE

Here are the commands to enter:

cd ~
mkdir HelloWeb
cd HelloWeb
touch startup.cs
touch project.json
code .

In Visual Studio Code, click on the startup.cs file on the left-hand side and then enter these statements:

using Microsoft.AspNet.Builder;
using Microsoft.Extensions.Logging;

namespace HelloWeb
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole();
            app.UseIISPlatformHandler();
            app.UseStaticFiles();
            app.UseWelcomePage();
        }
    }
}
