Description

C# Essentials is a practical, fast-paced course designed to bring experienced programmers up to speed with modern C# development. Focused on .NET 6, C# 10, and Visual Studio 2022, this three-day course explores how Microsoft’s unified platform simplifies application development across desktop, web, cloud, mobile, and IoT environments.

Built on the cross-platform .NET Core foundation, .NET 6 completes the platform unification initiated in .NET 5—enabling development on Windows, macOS, and Linux with a consistent set of tools and libraries.

This course is ideal for developers with prior programming experience who want to quickly gain proficiency in C#. Learners will explore key language features, object-oriented programming concepts, event handling, GUI creation with Windows Forms, and newer features like nullable reference types, record types, asynchronous programming, and top-level statements.

The course includes hands-on labs, real-world examples, and a cumulative case study to reinforce key concepts. All students receive comprehensive course materials and source code for every example.
