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.

Using ADO.NET


When Microsoft first created .NET, it had one data access technology, and it was named ADO.NET. Since then, Microsoft has added additional technologies but reused the name ADO.NET, so it can get confusing. The following are your two main choices today:

  • ADO.NET: This is the original .NET data access technology that has classes that inherit from abstract base classes such as DbConnection and DbDataReader. I often refer to this as classic ADO.NET.

  • ADO.NET Entity Framework: This is a layer on top of ADO.NET that adds object-relational mapping (ORM) capabilities. I often refer to this as Entity Framework or just EF.

Tip

Both are supported on .NET Core. Use classic ADO.NET for performance, to maintain existing code that already uses it, and when your tables must always be accessed through stored procedures instead of directly. Use Entity Framework when developer productivity is more important than performance and when you are allowed to execute dynamically generated SQL statements...
