We just posted new course on the freeCodeCamp.org that will teach you about authentication and authorization in ASP.NET applications, two concepts that are often confused but are fundamentally different. Ervis Trupja developed this course.

Before we can control who can do what, we first have to know who they are. This is where authentication comes in. Think of authentication as checking a user's ID card. It's the process of verifying a user's identity by checking their credentials, such as a username and password.

Once a user's identity is confirmed, authorization determines what they're allowed to do. It's like a bouncer at a club checking if your wristband gives you access to the VIP section. Authorization verifies a user's roles or permissions to ensure they can access specific resources or perform certain actions.

This comprehensive course is great for anyone looking to build secure, robust ASP.NET applications. You'll gain practical, hands-on experience covering a wide range of topics:

• Setting up Identity tables using Entity Framework Core.

• Configuring JWTs in your Startup.cs file.

• Creating a dedicated Authentication controller.

• Registering and logging in new users.

• Generating and managing access and refresh tokens.

• Implementing role-based authorization to control access to different parts of your application.

We just published a course on the freeCodeCamp.org YouTube channel that will teach you all about ASP.NET Core MVC and Entity Framework Core in .NET 9. This beginner-friendly, step-by-step tutorial, developed by Alen Omeri, will guide you through everything you need to know to start building dynamic web applications from scratch.

The course starts with an overview of ASP.NET Core MVC and explains the basics of the Model-View-Controller (MVC) pattern. You'll learn how to set up a development environment for .NET 9 and get familiar with the typical file structure of an ASP.NET Core MVC project. As you progress, you'll see MVC in action, understanding key concepts such as IActionResult, action parameters, and the Razor syntax, which is used to generate dynamic web pages.

One of the core focuses of the course is data management. You'll learn about Entity Framework Core, a powerful Object-Relational Mapper (ORM) that enables you to work with databases directly in C#. The course covers both code-first and database-first approaches, giving you flexibility in how you design your applications. You'll also get hands-on experience with CRUD operations (Create, Read, Update, Delete), which are fundamental for managing data in web apps.

In addition to these basics, the course takes a deeper dive into database relationships, including one-to-one, one-to-many, and many-to-many relationships, which are critical for building complex data models. These concepts will help you design databases that reflect real-world scenarios, ensuring your web applications can handle various user and data interactions.

By the end of this course, you'll have a strong foundation in ASP.NET Core MVC and Entity Framework Core and be ready to start building your own .NET applications. Watch the full course on the freeCodeCamp.org YouTube channel (2-hour watch).
