SOLID Design Principles in C# with Real-time Examples

In this SOLID Design Principles in C# with Examples 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 in C# 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 Design 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, 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 beginners as well as professionals developers who want to learn How to design good software using SOLID Design Principles in C# in a quick time, I have decided to start a series of articles on SOLID Design Principles with Real-time Examples.

Advantages of SOLID Design Principles in C#

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

Maintainability: 

Nowadays maintaining the software is the biggest challenge for the Industry. Day by day the business grows for the organization and as the business grows you 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 with minimum effort and 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.

What do you mean by SOLID Design Principles in C#?

The SOLID Design Principles in C# are the design principles that basically used to manage most of the software design problems that generally we encountered in our day-to-day programming. These design principles are provided with some mechanism that will make the software designs more understandable, flexible, and maintainable.

What is the main reason behind most of the unsuccessful applications?

The following are the main reasons for most of the software failures.

  1. Putting more functionalities on classes. (In the simple word a lot of functionalities we are putting into the class even though they are not related to the class.)
  2. Implementing Tight coupling between the classes. If the classes are dependent on each other, then a change in one class will affect the other classes also.
How to overcome the unsuccessful application Development problem?
  1. We need to use the correct architecture (i.e. MVC, Layered, 3-tier, MVP, and so on) as per the project requirements.
  2. As a developer, we need to follow the Design Principles (i.e. SOLID Principles).
  3. Again we need to choose the correct Design Patterns as per the project requirements.
Introduction to SOLID Design principles in C#

The SOLID Design principles are basically used to manage most of the software design problems that generally as a developer we face in our day-to-day programming. SOLID principles represent five design principles that basically used to make the software designs more understandable, flexible, and maintainable.

SOLID Acronym
  1. S stands for the Single Responsibility Principle which is also known as SRP.
  2. O stands for the Open-Closed Principle which is also known as OSP.
  3. L stands for the Liskov Substitution Principle which is also known as LSP.
  4. I stand for the Interface Segregation Principle which is also known as ISP.
  5. D stands for Dependency Inversion Principle which is also known as DIP.
What are the Advantages of using SOLID Design Principles in C#?

We will get the following advantages of using SOLID Design Principles in C#.

  1. Achieve the reduction in complexity of the code
  2. Increase readability, extensibility, and maintenance
  3. Reduce error and implement Reusability
  4. Achieve Better testability
  5. Reduce tight coupling

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 Design Principles in C# with Real-time Examples as we progress.
