Dive into C# and create apps, user interfaces, games, and more using this fun and highly visual introduction to C#, .NET Core, and Visual Studio. With this completely updated guide, which covers C# 8.0 and Visual Studio 2019, beginning programmers like you will build a fully functional game in the opening chapter. Then you'll learn how to use classes and object-oriented programming, create 3D games in Unity, and query data with LINQ. And you'll do it all by solving puzzles, doing hands-on exercises, and building real-world applications. By the time you're done, you'll be a solid C# programmer--and you'll have a great time along the way!

Based on the latest research in cognitive science and learning theory, Head First C# uses a visually rich format to engage your mind rather than a text-heavy approach that puts you to sleep. Why waste your time struggling with new concepts? This multisensory learning experience is designed for the way your brain really works.

Some of the chapters have downloadable projects. You can download PDFs of those projects here:

• Chapter_5_Blazor_projects.pdf – The two Blazor projects from Chapter 5
• Chapter_6_Blazor_project.pdf – The Blazor project from Chapter 5
• Chapter_8_WPF_project.pdf – The WPF project from Chapter 8
• Chapter_8_Blazor_project.pdf – The Blazor project from Chapter 8
• Chapter_9_project.pdf – The Go Fish! project from Chapter 9
• Chapter_10_project.pdf – The Hide and Seek project from Chapter 10
• Chapter_12_boss_battle.pdf – The Animal Match Game boss battle project at the end of the book

NOTE: The downloadable projects for these chapters are early release PDFs! That means that while the code works, the projects are complete, and we've done our initial review of them, we're still working on polishing them up and putting the final touches on them. But you can definitely start using them today!*

In the Head First C# Unity Labs you'll use Unity, the powerful platform for 2D and 3D game development, to explore C# and practice your C# skills.

• Unity_Lab_1.pdf – Explore C# with Unity
• Unity_Lab_2.pdf – Write C# Code for Unity
• Unity_Lab_3.pdf – GameObject Instances
• Unity_Lab_4.pdf – User Interfaces
• Unity_Lab_5.pdf – Raycasting
• Unity_Lab_6.pdf – Scene Navigation

There's more to learn about Unity! We've written additional Unity Labs that go beyond the material in the book to teach you important Unity topics, and give you more practice building 3D games.

• Unity_Lab_7.pdf – Physics
• Unity_Lab_8.pdf - Collision Detection (coming soon!)
• Unity_Lab_9.pdf - Unity Boss Battle (coming soon!)
• Unity_Lab_10.pdf - robots (coming soon!)

You can find the code for the Unity Lab projects in the Unity_Labs/Projcts folder. You can load a project into Unity by:

• Downloading it (or cloning this whole repository)
• Adding its folder to Unity Hub
• Opening it in Unity Hub
• Opening SampleScene from the Scenes folder

Here's what you'll find in this repository:

• Head_First_CSharp_4e_chapters_1_to_4.pdf – a PDF of the first four chapters, including the first two Unity Labs and the Visual Studio for Mac Learner's Guide appendix
• Unity Labs – PDFs and graphics files for the Unity Lab projects throughout the book
• Billiard Ball Textures – billiard ball textures for the Unity Lab projects

In the first chaper you jump right into a project to create an animal matching game to help you start learning about C# and Visual Studio. We've had many readers do this project—so don't worry, it definitely works! (In fact, some of our readers got especially creative with the project. You can read more about it on the Visual Studio blog.)

While most readers are able to do this project without any trouble, you could run into problems if your code doesn't match the code in the book exactly. Here's what to do if you run into trouble with the project in the first chapter:

• Compare the code line by line. It's really easy to miss a comma, semicolon, parentheses, equals sign, etc.
• If you're following the WPF version, make sure that your XAML matches the XAML in the book exactly. If you're missing a TextBlock, you'll get an ArgumentOutOfRangeException.
• If you're following the ASP.NET Blazor version, make sure that your HTML markup matches the markup in the book exactly.

If you're still having trouble, watch the video walkthrough for the project on our YouTube channel. It shows every step in the project so you can see exactly what you're supposed to do.

We worked really hard to make this book as error-free as possible! But we're only human, and we do occasionally make mistkaes. If you spot an error in the book, please use the O'Reilly errata page to let us know about it. That way it goes into a database so we can keep track of it and fix it in future printings.
