.NET Design Patterns

By: Praseed Pai, Shine Xavier

Overview of this book

Knowing about design patterns enables developers to improve their code base, promoting code reuse and making their design more robust. This book focuses on the practical aspects of programming in .NET. You will learn about some of the relevant design patterns (and their application) that are most widely used. We start with classic object-oriented programming (OOP) techniques, evaluate parallel programming and concurrency models, enhance implementations by mixing OOP and functional programming, and finally to the reactive programming model where functional programming and OOP are used in synergy to write better code. Throughout this book, we’ll show you how to deal with architecture/design techniques, GoF patterns, relevant patterns from other catalogs, functional programming, and reactive programming techniques. After reading this book, you will be able to convincingly leverage these design patterns (factory pattern, builder pattern, prototype pattern, adapter pattern, facade pattern, decorator pattern, observer pattern and so on) for your programs. You will also be able to write fluid functional code in .NET that would leverage concurrency and parallelism!

How can we even proceed without seeing our spell checker in action on a web page? For this, we need an ASP.NET Web API that provides the suggestions. We will reuse our earlier NorvigSpellCheckerModel class as-is for this:

    using System; 
    using System.Collections.Generic; 
    using System.Linq; 
    using System.Net; 
    using System.Net.Http; 
    using System.Web.Http; 
    using SpellChecker; 
 
    namespace MvcApplication1.Controllers 
    { 
      public class SearchContext 
      { 
        public string Lookup { get; set; } 
        public int Count { get; set; } 
      } 
      public class ValuesController : ApiController 
      { 
        ISpellCheckerModel _spellChecker =      
        NorvigSpellCheckerModel.Instance; 
        // GET api/values 
        public IEnumerable<string> Get([FromUri] SearchContext      
        context) 
        {...
