.NET is Microsoft’s free and open source framework for developing native software applications on Linux, macOS, and Windows. The power of cross-platform development allows developers to design, code, and run programs on a wide array of platforms.

This course is an introduction to developing .NET applications using C#. You’ll start start with a comprehensive review of C# and computer programming fundamentals: data types, conditionals, loops, methods, and more. You’ll then review the basics of object-oriented programming before diving into methods, exception handling, delegation, and events. With this foundation, you’ll continue building interfaces, collections, database operations, and multithreading. You’ll wrap up with process improvements using dynamic binding, garbage collection, and unmanaged resources.

By the end of this course, you’ll have hands-on experience with C# and .NET, and be ready to build applications using object-oriented programming principles on almost any platform.

Mastering C# and .NET

# Overview

Imagine we’re building an application to manage notes. We can add and delete notes. We want the user interface to update itself whenever an item is added or deleted. How do we know when this occurs?

A good approach is to use events. The `ObservableCollection<T>` is a collection just like `List<T>`, but it exposes the `CollectionChanged` event that is triggered whenever an item is added to or removed from the list.

> **Note:** The `CollectionChanged` event is also triggered when the whole collection or an item is replaced with a different one.

We can subscribe to this event and make the UI update itself. 

# Syntax and usage

We instantiate and use `ObservableCollection<T>` just like a list. The class resides in the `System.Collections.ObjectModel` namespace. After importing it, we can start using this class in our programs:

Learn about a collection with a built-in notification mechanism.
