Introduction to .NET Core
What is .NET Core?
.NET Core is an open-source, cross-platform framework developed by Microsoft. It allows developers to build modern, cloud-based, and internet-connected applications. Unlike the traditional .NET Framework, .NET Core is not limited to Windows; it supports macOS and Linux as well. This flexibility makes it an attractive choice for developers aiming to create versatile and scalable applications.
Why Choose .NET Core?
.NET Core offers several advantages over its predecessors:
- Cross-Platform Compatibility: Write once, run anywhere. Your applications can run on Windows, macOS, and Linux.
- Performance: .NET Core is designed to be fast and efficient, making it suitable for high-performance applications.
- Modularity: The framework is modular, allowing you to include only the components you need, resulting in lighter and more efficient applications.
- Open Source: Being open-source, .NET Core benefits from a vibrant community and continuous improvements.
Getting Started with .NET Core
Setting Up Your Development Environment
Before you start coding, you need to set up your development environment. Here are the steps to get you up and running:
- Install .NET Core SDK: Download and install the .NET Core SDK from the official Microsoft website. The SDK includes everything you need to develop, build, and run .NET Core applications.
- Choose an IDE: Visual Studio is the most popular IDE for .NET Core development. It offers a rich set of features, including IntelliSense, debugging, and integrated testing tools. Alternatively, you can use Visual Studio Code, a lightweight and free code editor.
- Install Extensions: If you’re using Visual Studio Code, install the C# extension to enhance your development experience with features like syntax highlighting and code snippets.
Creating Your First .NET Core Application
With your development environment set up, it’s time to create your first .NET Core application. Follow these steps:
- Open a Terminal: Navigate to the directory where you want to create your project.
- Run the Command: Use the dotnet new command to create a new project. For example, dotnet new console -n MyFirstApp will create a new console application named “MyFirstApp.”
- Navigate to the Project Directory: Use the cd MyFirstApp command to navigate to your project directory.
- Run the Application: Use the dotnet run command to build and run your application. You should see “Hello, World!” printed in the terminal.

Understanding the Basics
C# Programming Language
C# is the primary language used for .NET Core development. If you’re new to C#, start by learning the basics of the language, including syntax, data types, control structures, and object-oriented programming concepts.
.NET Core Fundamentals
Familiarize yourself with the fundamental concepts of .NET Core, such as the Common Language Runtime (CLR), Base Class Library (BCL), and the .NET Core CLI (Command Line Interface). Understanding these core components will give you a solid foundation for building .NET Core applications.
Building Web Applications with ASP.NET Core
ASP.NET Core is a framework for building web applications and APIs using .NET Core. It is highly modular and optimized for performance. Here’s how you can get started with ASP.NET Core:
- Create a New ASP.NET Core Project: Use the dotnet new webapp -n MyWebApp command to create a new web application project.
- Understand the Project Structure: Familiarize yourself with the project structure, including the Program.cs, Startup.cs, and wwwroot folder.
- Run the Application: Use the dotnet run command to build and run your web application. Open a browser and navigate to http://localhost:5000 to see your application in action.
Exploring Advanced Topics
Dependency Injection
Dependency Injection (DI) is a design pattern that allows you to inject dependencies into a class, making your code more modular and testable. ASP.NET Core has built-in support for DI, making it easy to implement this pattern in your applications.
Middleware
Middleware is a fundamental concept in ASP.NET Core. It allows you to handle requests and responses in a pipeline. Understanding middleware is crucial for building robust and scalable web applications.
Entity Framework Core
Entity Framework Core (EF Core) is an object-database mapper that enables .NET developers to work with a database using .NET objects. It supports LINQ queries, change tracking, updates, and schema migrations.

Building Real-World Applications
Creating a RESTful API
Building a RESTful API is a common requirement for modern web applications. ASP.NET Core makes it easy to create APIs using controllers and action methods. Here’s how you can get started:
- Create a New API Project: Use the dotnet new webapi -n MyApi command to create a new API project.
- Define Your Models: Create C# classes to represent your data models.
- Create Controllers: Implement controllers to handle HTTP requests and return responses.
- Configure Routing: Define routes to map HTTP requests to your controllers and action methods.
Implementing Authentication and Authorization
Security is a critical aspect of any web application. ASP.NET Core provides built-in support for authentication and authorization. You can use Identity, JWT, or OAuth to secure your applications.
Deploying Your Application
Once you’ve built your application, the next step is to deploy it. You can deploy your .NET Core applications to various platforms, including Azure, AWS, and Docker. Here’s a basic outline of the deployment process:
- Publish Your Application: Use the dotnet publish command to compile your application and prepare it for deployment.
- Choose a Hosting Platform: Select a hosting platform that supports .NET Core, such as Azure App Service or AWS Elastic Beanstalk.
- Deploy Your Application: Follow the platform-specific instructions to deploy your application.
