As software ages, it becomes brittle: difficult to understand, fix, manage, use and improve. Developers working with many platforms have encountered this problem; now, developers working with Microsoft’s .NET are facing it as well. In Reengineering .NET, leading .NET architect Bradley Irby introduces proven best practices for revitalizing older .NET code and integrating new architectural and development advances into business-critical systems that can’t go offline. Using a step-by-step approach, .NET professionals can make legacy enterprise software more reliable, maintainable, attractive, and usable – and make it easier to upgrade for years to come.
Through real-world case studies and extensive downloadable sample code, Irby shows how to carefully plan a .NET reengineering project, understand the true current state of your code, introduce unit testing and other agile methods, refactor to services and controllers, and leverage powerful .NET reengineering tools built into Microsoft Visual Studio 2012.
This book is an indispensable resource for all developers, architects, and project managers responsible for existing .NET code bases and for a wide audience of non-technical managers and CTOs who want to understand the unique challenges faced by .NET teams involved in application or system reengineering projects.
