Beginning Visual C#

Beginning Visual C# is ideal for beginners with little background in programming, or relatively inexperienced programmers who want to move from a language that doesn't support object-oriented programming techniques. The book moves at a fast enough pace that if you have programmed in another language, then you will still find the book valuable.You will need to have access to either Visual Studio .NET or Visual C# .NET Standard Edition.

Beginning Visual C# is a new edition of this book, and is fully compatible with the final release of the .NET Framework. We strongly recommend that you order the new edition, Beginning Visual C# in preference to this edition. C# is Microsoft's brand new programming language for its new platform, the .NET Framework. The .NET Framework consists of a runtime environment for managing the execution of our code, and a whole host of class libraries for performing almost any programming task you can think of. Although .NET code can be written in many languages, C# is the only language designed specifically for the .NET Framework, and as such is set to become the language of choice for writing .NET applications for years to come. This book will be an indispensable guide as you learn to write C# programs, gradually explaining the key concepts of C# and .NET as your skills develop. After a thorough explanation of the basics of the C# language, we take an in-depth look at object-oriented programming in C#, before moving on to see how we write Windows applications in C#. We also show how you can create dynamic web pages and web services in C#. Finally, two case studies provide full examples of C# applications in action and show how it all ties together.
