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.

Writing and calling methods


Methods are type members that execute a block of statements. A method that performs some actions but does not return a value is marked as returning void. A method that performs some actions and returns a value is marked as returning the type of that return value.

Inside the Person class, statically import the System.Console type and then add the following code:

// methods
public void WriteToConsole()
{
    WriteLine($"{Name} was born on {DateOfBirth:dddd, d MMMM yyyy}");
}
public string GetOrigin()
{
    return $"{Name} was born on {HomePlanet}";
}

Inside the Main method, add the following code:

p1.WriteToConsole();
WriteLine(p1.GetOrigin());

Run the application and view the output:

Bob Smith was born on Wednesday, 22 December 1965
Bob Smith was born on Earth

Methods can have parameters passed to them in order to change their behavior. Parameters are defined a bit like variable declarations but inside the parentheses of the method.

Inside the Person class, add the following...
