Description

Course OverviewThis course provides a comprehensive overview of Design Patterns in C# and .NET from a practical perspective. This course in particular covers patterns with the use of:

The latest versions of C# and the .NET framework
Use of modern programming approaches: dependency injection, reactive programming and more
Use of modern developer tools such as ReSharper
Discussions of pattern variations and alternative approaches

This course provides an overview of all the Gang of Four (GoF) design patterns as outlined in their seminal book, together with modern-day variations, adjustments, discussions of intrinsic use of patterns in the language.

What are Design Patterns?

Design Patterns are reusable solutions to common programming problems.

The appeal of design patterns is immortal: we see them in libraries, some of them are intrinsic in programming languages, and you probably use them daily even if you don’t realize they are there.

What Patterns Does This Course Cover?

This course covers all the GoF design patterns. Here’s the full list of what is covered:

SOLID Design Principles: Single Responsibility Principle, the Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle
Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton
Structural Design Patterns: Adapter, Bridge, Composite, Decorator, Façade, Flyweight, and Proxy
Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Null Object, Observer, State, Strategy, Template Method and Visitor

Who Is the Course For?

This course is for .NET/C# developers who want to see not just textbook examples of, but also the different variations and tricks that can be applied to implement in a modern way.
For example, the introduction of the DLR allows us to use an ImpromptuObject so that our DynamicObject exposes any interface we desire.

Presentation Style

Most demos are single-file, so you can download the file attached to the lesson and run it in Visual Studio, Visual Studio Code, Rider or another IDE of your choice.

This course does not use UML class diagrams; all of the demos are live coding. I use Visual Studio, various NuGet packages, R# unit test runner and even dotMemoryUnit.
