C# is one of the most popular programming languages in the world, and its latest stable version, C# 10, has several new features and updates that make it an excellent choice for a wide variety of applications. Combined with the .NET framework, C# can empower developers to build native applications for all the major consumer operating systems as well as the cloud.

The course starts with an introduction to programming concepts such as conditional statements, loops, arrays, and functions. You’ll explore advanced topics of object-oriented programming (OOP) including classes, inheritance, access, and extensions. Finally, you’ll work with data structures, events, concurrency, testing, and databases.

By the end of this course, you’ll have a working knowledge of not only the C# programming language, but also key ideas of software engineering. You’ll also be prepared to build and deploy native applications with the .NET framework.

Programming Fundamentals: Getting Started with C# and .NET

## What is an ```event```?
**Events** allow classes to notify other classes when something occurs. Graphical User Interfaces (GUI) applications often use events to indicate when something occurs. One example is when a button is pressed and another class is listening to handle that `event`. There are multiple components to an event. Each component is discussed with example syntax below. Following these syntaxes, there's an example with all the components combined.

An **event** needs to be defined inside a class. Using the ```event``` keyword enables others to attach to this event. Specify the `delegate` type for the type of methods that can be attached to the `event`. In the example below, a predefined delegate called ```EventHandler``` is used. The ```EventHandler``` delegate returns ```void``` and has two parameters ```(object, EventArgs)```. The ```object``` is the sender (what sent the event) and the ```EventArgs``` object(contains basic information about the event).
