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.

## What is a lambda?
A **lambda** is essentially a method without a declaration; it uses clear and short syntax. A lambda can be written as a shorthand method directly in the place it's intended to be used. This is especially useful on small methods that are used only once. The lambda operator is ```=>```, and can be read as *goes to*. The lambda operator separates the expression into two parts (left side parameter, right side lambda body).

## Syntax
```C#
ANewNumber addFive = x => x + 5;
```

## Example: Lambda using a `delegate`
