SOLID Design Principles in C# with Real-time Examples

In these SOLID Design Principles in C# article series, I am going to discuss the examples by taking some real-time scenarios using different types of .net applications which include ASP.NET MVC, Web API, and Console Applications.

The SOLID Design Principles are the design principles that help us to solve most of the software design problems. These design principles provide us with multiple ways to move the tightly coupled code between the software components which makes the software designs more understandable, flexible, and maintainable

For whom:

These tutorials are design for beginners as well as professionals developers who want to learn SOLID Design Principles in C# step by step with real-time examples. This tutorial provides you with a hands-on approach to the subject with step-by-step programming examples that will assist you to learn and put the acquired knowledge into practice.

Why do we need SOLID Principles?

As a developer, we start developing applications using our experience and knowledge. But over time, the applications might arise bugs. We need to alter the application design for every change request or for a new feature request. After some time we might need to put a lot of effort, even for simple tasks and it might require the full working knowledge of the entire system. But we can’t blame change or new feature requests as they are part of the software development. We can’t stop them and refuse them either. So who is the culprit here? Obviously, it is the design of the application.

So, by considering the above problem and helping the beginners as well as professionals developers who want to learn How to design good software using SOLID Design Principles in a quick time, I have decided to start a series of articles on SOLID Design Principles.

Advantages of SOLID Principles in C#

As a developer, while you are designing and developing any software applications, then you need to consider the following points.

Maintainability: 

As we know, nowadays maintaining software is very important for organizations. Day by day the business may grow for the organization and you may need to enhance the software with new changes. So you need to design the software in such a way that it should accept future changes without any problem.

Testability:

Test-Driven Development (TDD) is one of the most important key aspects nowadays when you need to design and develop a large-scale application. We need to design the application in such a way that we should test each individual functionalities. 

Flexibility and Extensibility:

Nowadays flexibility and extensibility, both are very much required for enterprise applications. So we should design the application in such a way that it should be flexible so that it can be adapted to work in different ways and extensible so that we can add new features easily with minimum modifications.

Parallel Development:

The Parallel Development of an application is one of the most important key aspects. As we know it is not possible to have the entire development team will work on the same module at the same time. So we need to design the software in such a way that different teams can work on different modules.

The SOLID Design Principles and Design Patterns play an important role in achieving all of the above key points.

In this article series, I am going to cover all the features of SOLID Design Principles in C# with real-time examples. You will learn from the basic to advance level features of SOLID Principles as we progress. The following are the articles.

Single Responsibility Principle

Open Closed Principle

Liskov Substitution Principle
