LINQ is the part of the . NET Framework that provides a generic approach to querying data from different data sources. It has quickly become the next must-have skill for . NET developers. Pro LINQ: Language Integrated Query in C# 2010 is all about code. Literally, this book starts with code and ends with code. Most books show the simplest examples of how to use a method, but they so rarely show how to use the more complex prototypes. This book is different. Demonstrating the overwhelming majority of LINQ operators and prototypes, it is a veritable treasury of LINQ examples. Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in writing, this book cuts right to the chase of each LINQ operator, method, or class. However, where complexity is necessary to truly demonstrate an issue, the examples are right there in the thick of it. For example, code samples demonstrating how to handle concurrency conflicts actually create concurrency conflicts so you can step through the code and see them unfold. Face it, most technical books, while informative, are dull. LINQ need not be dull. Written with a sense of humor, this book will attempt to entertain you on your journey through the wonderland of LINQ and C# 2010.

Mastering the development of . NET 4.0 applications in C# is less about knowing the Visual C# 2010 language and more about knowing how to use the functionality of the . NET framework class library most effectively. Visual C# 2010 Recipes explores the breadth of the . NET Framework class library and provides specific solutions to common and interesting programming problems. Each recipe is presented in a succinct problem/solution format and is accompanied by a working code sample to help you understand the concept and quickly apply it. When you are facing a Visual C# 2010 problem, this book likely contains a recipe providing the solution—or at least points you in the right direction. Even if you are simply looking to broaden your knowledge of the . NET framework class library, Visual C# 2010 Recipes is the perfect resource to assist you. This is an updated reference for . NET 4.0 programmers. All code samples come as stand-alone Visual Studio 2010 solutions for your convenience.

With the spread of Web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that . NET forces you to address, since Microsoft has placed security-related features at the core of the . NET Framework. Yet, because a developer's carelessness or lack ofexperience can still allow a program to be used in an unintended way, Programming . NET Security shows you how the various tools will help you write secure applications. The book works as both a comprehensive tutorial and reference to security issues for . NET application development, and contains numerous practical examples in both the C# and VB. NET languages. With Programming . NET Security, you will learn to apply sound security principles to your application designs, and to understand the concepts of identity, authentication and authorization and how they apply to . NET security. This guide also teaches you to: use the . NET run-time security features and . N ET security namespaces and types to implement best-practices in your applications, including evidence, permissions, code identity and security policy, and role based and Code Access Security (CAS); use the . NET cryptographic APIs , from hashing and common encryption algorithms to digital signatures and cryptographic keys, to protect your data; and use COM+ component services in a secure manner. If you program with ASP. NET will also learn how to apply security to your applications. And the book also shows you how to use the Windows Event Log Service to audit Windows security violations that may be a threat to your solution.
