Based on the principles of cognitive science and instructional design, Fluent C# is a true tutorial that helps you build effective working models for understanding a large and complex subject: developing .NET Framework applications with C#. Unlike so-called "tutorials" that merely describe the material briefly, and offer an "exercise" that merely requires typing in already-provided source code, this book's carefully paced exercises closely align with the brain's natural learning processes. You will discover the material yourself- and absorb it more rapidly and effectively. Fluent C# successfully introduces you to the principles and concepts you need to use Object-Oriented Programming, Test-Driven Development, design patterns, and even the Microsoft Architectural Guidelines for building effective .NET software. It also teaches powerful C# 4.0 techniques for building presentation layers with WPF; business layers that incorporate workflow, activities, and services; and data access layers that utilizing the Entity Framework and LINQ. This book's breadth is impressive. More important, its open, inviting graphical format and exercise-driven learning approach makes learning these complex topics easier and more natural than it's ever been before.
