This book is for beginners as well as intermediate-level C# and .NET programmers who have worked with C# in the past and want to catch up with the changes made in the last few years.

Prior exposure to C# or .NET is not a prerequisite. A general understanding of programming will help you to work through the book more comfortably, though the content is suitable for those completely new to programming.

If you already have some C# and .NET skills and want to focus on developing practical apps, you can pick up Mark's other .NET book, Apps and Services with .NET 8, instead.
