SummaryDependency Injection Principles, Practices, and Patterns teach you to use DI to reduce hard-coded dependencies between application components. You will start by learning what DI is and what types of applications would benefit from it. Next, you'll work on concrete scenarios using the C# and .NET framework to implement DI in your own projects. As you dive into the examples described in detail, you'll develop a foundation that you can apply to any of the many DI libraries for .NET and .NET Core.Purchase of the print book includes a free eBook from Manning Publications in PDF, Kindle, and ePub formats.About TechnologyDependency Injection (DI) is a great way to reduce tight coupling between software components. Instead of hardcoding dependencies like specifying a database driver, you make these connections through a third party. At the heart of application frameworks like ASP.NET Core, DI allows you to better manage changes and other complexities in your software.
