Completely updated for C# 6.0, the new edition of this bestseller offers more than 150 code recipes to common and not-so-common problems that C# programmers face every day. More than a third of the recipes have been rewritten to take advantage of new C# 6.0 features. If you prefer solutions to general C# language instruction and quick answers to theory, this is your book.C# 6.0 Cookbook offers new recipes for asynchronous methods, dynamic objects, enhanced error handling, the Rosyln compiler, and more.

Here are some of topics covered:

Classes and generics

Collections, enumerators, and iterators

Data types

LINQ and Lambda expressions

Exception handling

Reflection and dynamic programming

Regular expressions

Filesystem interactions

Networking and the Web

XML usage

Threading, Synchronization, and Concurrency

Each recipe in the book includes tested code that you can download from oreilly.com and reuse in your own applications, and each one includes a detailed discussion of how and why the underlying technology works. You don't have to be an experienced C# or .NET developer to use C# 6.0 Cookbook. You just have to be someone who wants to solve a problem now, without having to learn all the related theory first.
