The book "C# 2010: Crash Course for Professionals" is a guide to creating effective code in C# 4.0. It shows how to write programs that are reliable, error-tolerant, and ready to be included in widely available libraries. The book offers a well-organized and easy-to-read text covering C# 2010 and the well-tried and true idioms, patterns, and design principles that have matured in the object-oriented arena throughout the life of the .NET Framework. Numerous short examples demonstrate the regular use of common design patterns in the .NET Framework and show how to use them in your own development. This book covers in detail all the new features of the C# language, including dynamic types, covariance and contravariance, extension methods, lambda expressions, LINQ language and many others. New dynamic types significantly simplify the implementation of interaction tools that were previously difficult to create. Extension methods, lambda expressions, and the LINQ language encourage the use of a functional programming model within what was previously a primarily imperative programming language. Once you start using them, you will quickly experience how your ability to build solutions has expanded. Another area of interest for C# developers is writing exception-safe and error-tolerant code. The .NET Framework supports many features, including limited scopes executions that help protect application state in the event of an asynchronous exception. All these possibilities are also discussed in the book. Happy programming, and remember that defining the contract before implementation, striving for exception-neutral code, and using resources sparingly are the keys to a successful product. This book by a leading .NET expert is a crash course in the latest version of the C# language, embodies important additions and offers an environment in which functional programming can be seamlessly intertwined with the usual style of imperative programming in C#. This book can serve as both a short study guide and an ongoing reference. You will quickly master the C# syntax, exploring how the CLR simplifies many programming tasks. You'll also receive a wealth of guidance on how to build efficient, reusable, and reliable code. Why spend months or even years researching the best approaches to designing and writing C# code when this book shows you how to do it right from the start? You'll learn how

C# works and interacts with the CLR; use arrays, collections, and iterators; handle events using delegates and anonymous functions; design and use generic types and methods; build highly efficient and reliable multi-threaded applications; apply anonymous types, lambda expressions and extension methods that appeared in C#.

The book is intended for programmers of various qualifications, as well as will be useful to students and teachers of disciplines related to programming and development for .NET.
