This chapter contains various code examples to explain these concepts. The code is kept simple and is just for demonstration purposes. Most of the examples involve a .NET Core console application written in C#.

To run and execute the code, you will need the following:

• Visual Studio 2019 (you can also run the application using Visual Studio 2017 version 3 or later)
• .NET Core
• SQL Server (the Express Edition is used in this chapter)
