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 method?
A **method** is a small group of reusable code that carries out a single task. To use a method, define the method and call (invoke) the method when needed. Methods can be called an unlimited number of times.

The following is the full syntax for the defined method:
```C#
public static int Add2Numbers(int num1, int num2)
```

- **Access Modifier:** The access modifier determines the visibility of the method, meaning classes have access to them. Examples include ```public```, ```internal```, ```private```, and ```protected```. If an access modifier isn't declared, it's ```private``` by default.

- **Static Modifier:** `static` methods are shared by all instances of the class, meaning that the method can be accessed directly from the class name. If ```static``` isn't declared, it's non-static by default.

- **Return Type:** A method can return a value type (```int```, ```string```, ```bool```) or ```void``` in the absence of a return value. A return type must be specified.

- **Name:** Method names are required.

- **Parameters:** Arguments (values) are passed to parameters in methods. Parameters are optional.
