When you’re programming C# 4.0 and need a little help, this tightly focused and practical book tells you exactly what you need to know without long introductions or bloated examples. It’s ideal as a succinct quick reference or as a guide to get you rapidly up to speed if you already know Java, C++, or an earlier version of C#. Written by the authors of the acclaimed *C# 4.0 in a Nutshell* (O’Reilly), this book covers the entire C# 4.0 language without skimping on the details including: * Features new to C# 4.0, such as dynamic binding, optional and named parameters, and type parameter variance * All of C#’s fundamentals * Advanced topics, including operator overloading, custom conversions, type constraints, covariance and contravariance, lambda expressions and closures, iterators, nullable types, and operator lifting * LINQ, starting with sequences, lazy execution, and standard query operators; finishing with a complete reference to query expressions * Unsafe code and pointers, custom attributes, preprocessor directives, and XML documentation
