Few .NET developers have the luxury of unlimited code testing once their application is complete, and rushing through the testing process is both problematic and stressful. The open source NUnit framework provides an excellent and efficient way to test and improve .NET code as it's written, saving hundreds of QA hours and headaches.NUnit is one of the most mature and widely-used .NET open source projects even Microsoft uses it internally. NUnit is a unit-testing framework for all .Net languages. Written entirely in C#, NUnit takes advantage of many .NET language features, such as custom attributes and other reflection related capabilities. It automates unit testing and reduces the effort required to frequently test code while developing it. NUint is invaluable for .NET developers in test-driven development under agile methodologies such as Extreme Programming (XP) as well as for developers who use for unit testing for software quality assurance. Unfortunately, some of those valuable hours saved by using NUnit can be wasted trying to master this powerful but under-documented frameworkProof that good things come in small packages, the NUnit Pocket Reference is a complete reference to NUnit, filling in the blanks left by the existing documentation and online discussion. It offers developers everything they need to know to install, configure, and use NUnit; the NUnit user interface; and a reference to the NUnit framework classes in a slim but well-organized package. This handy little book even offers practical, real world NUnit examples. And with the NUnit Pocket Reference, IT managers will know to expect when they implement unit testing in their projects. It is the only book you'll need on this popular and practical new open source framework.

LINQ represents a paradigm shift for developers used to an imperative/object oriented programming style, because LINQ draws on functional programming principles. Thinking in LINQ addresses the differences between these two by providing a set of succinct recipes arranged in several groups, including: Basic and extended LINQ operators Text processing Loop refactoring Monitoring code health Reactive Extensions (Rx.NET) Building domain-specific languages Using the familiar "recipes" approach, Thinking in LINQ shows you how to approach building LINQ-based solutions, how such solutions are different from what you already know, and why they’re better. The recipes cover a wide range of real-world problems, from using LINQ to replace existing loops, to writing your own Swype-like keyboard entry routines, to finding duplicate files on your hard drive. The goal of these recipes is to get you "thinking in LINQ," so you can use the techniques in your own code to write more efficient and concise data-intensive applications.

Microsoft’s Dynamic Language Runtime (DLR) is a platform for running dynamic languages such as Ruby and Python on an equal footing with compiled languages such as C#. Furthermore, the runtime is the foundation for many useful software design and architecture techniques you can apply as you develop your .NET applications. Pro DLR in .NET 4 introduces you to the DLR, showing how you can use it to write software that combines dynamic and static languages, letting you choose the right tool for the job. You will learn the core DLR components such as LINQ expressions, call sites, binders, and dynamic objects—and how they work together to achieve language interoperability. You’ll see how to mix and match objects and functions from compiled and dynamic languages, so you can write code in the language of your choice while taking advantage of libraries written in other languages. And you'll discover how the various languages interoperate behind the scenes. With the basics out of the way, the book then details the various ways you can leverage the DLR in the design and architecture of your software applications. You’ll learn about runtime code generation, which lets you avoid much of the boilerplate code typical in layered business applications. You’ll see practical examples of using the DLR to build domain-specific languages, and you’ll learn how the DLR helps enable aspect-oriented programming.
