# C# Introduction

> Learn object-oriented programming in C# and .NET, from the basics to classes, interfaces and inheritance.

## Workshop facts

- **Duration:** 3 days or 6 half days
- **Level:** Beginner
- **Language:** English, Swedish

This workshop introduces the C# language and .NET to developers who already program in another object-oriented language. We start with the basics and work up to classes, collections and inheritance, so you get a solid foundation for working as a C# developer. It is up to date with C# 14 and .NET 10.

The workshop mixes presentations, demonstrations and hands-on exercises, so you both understand the concepts and practise using them.

### Who Is This Workshop For?

Software developers who want to start programming in C# on the .NET platform, whether you are switching from another object-oriented language or broadening your skills.

### Prerequisites

Programming experience in any object-oriented language. You don't need any prior knowledge of C#, .NET or Visual Studio.

### Workshop Agenda

During the workshop, we cover C# in three parts.

#### Part 1
