Overview of this book

When you are developing on the Microsoft platform, Visual Studio 2010 offers you a range of powerful tools and makes the whole process easier and faster. After learning it, if you are think that you can sit back and relax, you cannot be further away from truth. To beat the crowd, you need to be better than others, learn tips and tricks that other don't know yet. This book is a compilation of the best practices of programming with Visual Studio. Visual Studio 2010 best practices will take you through the practices that you need to master programming with .NET Framework. The book goes on to detail several practices involving many aspects of software development with Visual Studio. These practices include debugging and exception handling and design. It details building and maintaining a recommended practices library and the criteria by which to document recommended practices The book begins with practices on source code control (SCC). It includes different types of SCC and discusses how to choose them based on different scenarios. Advanced syntax in C# is then covered with practices covering generics, iterator methods, lambdas, and closures. The next set of practices focus on deployment as well as creating MSI deployments with Windows Installer XML (WiX)óincluding Windows applications and services. The book then takes you through practices for developing with WCF and Web Service. The software development lifecycle is completed with practices on testing like project structure, naming, and the different types of automated tests. Topics like test coverage, continuous testing and deployment, and mocking are included. Although this book uses Visual Studio as example, you can use these practices with any IDE.

Preface

Working with extension methods


Along with lambda expressions and iterators, C# 3.0 brought us extension methods. These static methods (contained in a static class whose first argument is modified with the this modifier) were created for LINQ so IEnumerable types could be queried without needing to add copious amounts of methods to the IEnumerable interface.

An extension method has the basic form of:

public static class EnumerableExtensions
{
public static IEnumerable<int> IntegerSquares(
this IEnumerable<int> source)
{
return source.Select(value => value * value);
}
}

As stated earlier, extension methods must be within a static class, be a static method, and the first parameter must be modified with the this modifier.

Extension methods extend the available instance methods of a type. In our previous example, we've effectively added an instance member to IEnumerable<int> named IntegerSquares so we get a sequence of integer values that have been squared.

For example, if...
