Summary  
This chapter covers delegates: types that represent references to methods with specific signatures, enabling passing methods as arguments, storing multiple method references, chaining their execution, and retrieving return values (with the last method’s result returned when multiple methods are chained).

General domain of usage  
Callback and event handling mechanisms

### Important Points:
- Delegates are types that can reference methods of a certain kind of signature;
- Delegates allow us to pass methods as arguments;
- The syntax of a creating a new **delegate type** is as follows: `delegate <return type> <type name> (parameter1, parameter2, …);`;
- We can create a variable using a delegate type and assign it a method reference using the following syntax: `DelegateTypeName variableName = methodName;`;
- More methods can be added to a **delegate instance** using the `+=` operator;
- Methods can be removed from a **delegate instance** using the `-+` operator;
- In case there are multiple methods in a delegate instance that return a value, **the value of the last executed method is returned**;


Which of the following is a correct syntax to declare a delegate named "MyDelegate" that takes an integer parameter and returns void?

In this course, we will learn about some advanced C# concepts along with MAUI, which is an application development library. We will learn how to create some interesting GUI applications while keeping them quick and responsive using techniques like Threading. We will make applications that will interact user input and APIs, and apart from that, we will cover some important C# concepts like Reflection and Generics. This course will further improve our programming skills and will give us a strong foundation to move forward towards Web Development.
