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 ```dictionary```?

A **dictionary** consists of a *key* and a *value*. In an array, the key is created automatically (0, 1, and so on). With dictionaries, the key name can be set to something meaningful. As with lists, **dictionaries** use *generics*.

To use a dictionary, add the following line of code:
```C#
using System.Collections.Generic; // C# 10 comes with ImplicitUsings, meaning the most popular using namespaces such as this one is already built-in so there is no need to declare it
```

## Example: Instantiate and assign items to a dictionary
Dictionaries have two generic data type parameters. Because they're generic, any data type can be entered. In the example below, the first generic data type is a ```string``` and is used as the *key*. The second generic data type is an ```int```, and ```string``` is used for the *value*.
