Description

With this course, you will learn the bare-bone basics of C# by building console applications from scratch. You will first develop the application and then test it to gain a solid understanding of C# fundamentals. You will also explore the latest features released in C# 7.

To learn a programming language, it is crucial to understand the basic and fundamental concepts. Most of the courses teach the fundamentals with raw theory and this makes the learning boring. But not this video course. With this course, you will learn the basic concepts of C# by building console applications from the beginning. The course starts by making you ready to build applications in C# by guiding you through the installation process of Visual Studio Community 2022, and by teaching you how to handle updates and do self-troubleshooting. Once you are up with Visual 2022, you will program interesting console applications such as a simple calculator, word unscrambler, simple web scraper, and sudoku solver. By building all these applications, you will become friendly with C# core concepts such as acceptance criteria, algorithm, flowchart, variables, expressions and operators, objects and classes, methods, arrays, loops, constructors, exception handling, unit testing, and a lot more C# topics. Toward the end, you will find out what's new in C# 7 and how you can use the updated features in application building. By the end of this course, you will have developed basic C# skills that are needed for building simple .NET console applications.
