Object-Oriented Programming (OOP) gives the power to developers to make their code scalable, readable, and maintainable. These are the main aspects that an organization looks at before hiring a software developer or a web developer. And these aspects are what make a developer stand out from the rest of the herd. OOP teaches you how to think clearly about your code by letting you visualize your problems in terms of objects. This allows you to have a high-level view of the problem which then allows you to come up with a much better solution. The course starts with an overview of learning objectives and guides you through the process of installing .NET Core, Visual Studio Code, and C# plugins in Visual Studio. Once you are good to go, you will uncover what a program is and some great ways to write an error-free program. You will also become familiar with Object Oriented Programming (OOP) basics. Now, with the help of simple examples, you will understand the four main pillars of OOP: inheritance, polymorphism (static and dynamic), encapsulation, and abstraction. Towards the end, you will recap all that you have learned, and develop three small applications to encapsulate your learning. By the end of this course, you will be well-versed in Object Oriented Programming (OOP) fundamentals using C# and .NET as the coding platform.
