Who this book is for
This book is for anyone who wants to learn the C# programming language:
- It works if you’re new to programming.
- It works if you’re new to .NET development.
- It works if you’re an experienced .NET developer who’s new to C#.
- It works if you have programming experience with another language like Java, C++, or Python.
- And it works if you’ve already read 3 or 4 other C# books and still don’t know how to develop a real-world business application.
Why this is the C# book that you should buy first
This is a great first book in C#, whether you’re a programming novice or an experienced programmer. Here are 5 reasons why that’s true.
#1: A FAST start, coupled with Visual Studio productivity
This book starts you off using all the best features of Visual Studio so you can begin productive work almost immediately. In fact, it has you create a simple business application in chapters 2 and 3 so you can see right away how the essential features of C#, Visual Studio, and .NET work.
#2: Object-oriented programming made clear
When it comes to object-oriented programming, too many C# books resort to whimsical metaphors, like illustrating objects by creating animal classes such as mammals, cats, and dogs. But then, they leave it up to you to figure out how to transfer these concepts to business applications.
In contrast, this book presents business objects such as customers, invoices, and products so you can see how OOP is used to create multi-tiered applications in the real world.
#3: Confidence in handling business requirements
Learning to use C# classes and OOP techniques isn’t enough. You also have to know how to code for the tasks that are required in most business applications.
That’s why this book builds on your skills in incremental steps to teach you how to validate data; handle numeric, date, and string data; work with loops, arrays, and collections; code methods and event handlers; handle exceptions; and work with files and databases.
#4: A solid grounding in database programming
You can’t create business applications without handling databases.
So this book teaches you how to create database applications using Entity Framework (EF) Core and ADO.NET code. And it shows how to use LINQ, a feature that lets you query almost any data structure…not just databases…using the C# language.
This is powerful stuff that’s glossed over in most other C# books.
#5: Real-world applications tie it all together
This book presents complete, non-trivial applications that illustrate what you need to know on the job. Studying applications like these is the key to mastering C# development, but you won’t find them in many other C# books.
What’s new in this edition
C# is a mature product. So the basics of developing Windows applications using C# and Visual Studio haven’t changed since the previous edition.
Having said that, this book has been thoroughly updated to include coverage of the most helpful new features from the latest releases of C#, .NET, and Visual Studio…and to delete any material that’s becoming obsolete. So you can be sure that it focuses on the features you’ll use every day in creating C# apps.
What software you need for this book
To develop the Windows Forms applications presented in this book, you need the following:
Windows 7 SP1 or later (Windows 10 or later recommended)
Although .NET is cross-platform, you can’t use macOS or Linux to develop Windows Forms applications like the ones shown in this book. You have to have a Windows system.
Visual Studio Community 2019 or later
The Community edition of Visual Studio can be downloaded for free from Microsoft’s website. When you install it, you can also install all of the components that you need to work with this book, including:
- .NET
- The compiler for the C# language
- SQL Server Express LocalDB
Appendix A provides detailed installation instructions.
If you already have another edition of Visual Studio installed on your system, such as the Professional edition, you can use that if you prefer. Everything in our book will still work for you.
What people say about this book
"Best C# book ever. Murach manuals are precise and to the point, with lots and lots of examples. Highly recommended for beginners."
- Posted at an online bookseller
"Murach has yet again hit a home run! This book is laid out in such a way where the theory is on the left page and the ‘Cliff Notes’ version of the content is on the right side. It gets you from zero to Jr Dev knowledge in no time. After the fact, you can always use that right page as a great reference whilst in the middle of a project. Bravo again, guys."
- Brian Knight, Founder, Pragmatic Works, Florida
"A notable feature of the book is that everything is done as a ‘How to,’ which is great when you are learning. This is the typical Murach approach to books, making them not just useful for learning but also as big cookbooks."
- David Bolton, Past Host of C/C++/C# for About.com (now hosted at ThoughtCo.com)
“This is my first Murach book. For starters, I really like the format. It made it easy to understand the material as I was going through it. And speaking of material in the book, it covers a lot. I feel it will make a good reference for any future projects I may encounter.”
- Posted at an online bookseller
"Just trying to learn a development language can be daunting, and you can spend hours trying to find the answer to rather straightforward questions, like working with arrays. This book brings it all together in a comprehensive manner that is easy to understand and follow."
- Hal Hayes, Capital Area .NET User Group
“I am pretty critical of most authors, because they write fluff...and they present very little code. Not Murachs's. Most of the C# books I have purchased received a 3/5 star rating. Murach's is 5/5. I would buy this again.”
- Posted at an online bookseller
"Murach’s books have always impressed me, and Murach’s C# is no exception. It is an excellent source for those looking to learn C#, and there is much included that will benefit existing C# programmers as well. The examples and projects are relevant in a business setting and are complete. It is well worth adding this book to your programming reference collection."
- Jamie McMahon, DreamInCode.net
“I have learned more in the 800+ pages of this book than I have reading half a dozen other books and hours of forum posts online.”
