ASP NET Core vs Code Tutorial: Ultimate Guide for Beginners 2024

If you're exploring web development and want to leverage the power of .NET with a modern, cross-platform framework, you've likely found yourself comparing ASP.NET Core and Visual Studio Code (VS Code). This tutorial delves into these two powerhouses, explaining how they complement each other and guide you through creating a simple ASP.NET Core web application using VS Code.

Before diving in, ensure you've installed both ASP.NET Core (latest version) and VS Code on your machine. Having a fundamental understanding of C# and HTML will also be beneficial. Let's embark on this journey, starting with the basics of ASP.NET Core and VS Code.

Understanding ASP.NET Core and Visual Studio Code

ASP.NET Core is an open-source, high-performance, cross-platform framework for developing modern, cloud-based, and Internet-connected applications. It supports multiple platforms, including Windows, Linux, and macOS. VS Code, on the other hand, is a free, open-source, multi-platform code editor developed by Microsoft. It comes packed with features like built-in Git support, IntelliSense, rich snippets, and more, making it an excellent choice for developing ASP.NET Core applications.

ASP.NET Core and VS Code are a match made in heaven. ASP.NET Core provides the platform and tools, while VS Code offers a flexible, extensible, and feature-rich environment to build your applications efficiently.

Setting Up Visual Studio Code for ASP.NET Core

VS Code is already prepared for ASP.NET Core out of the box with built-in support for C#. However, to enhance your development experience, let's install the additional C# for Visual Studio Code extension:

• Launch VS Code.
• Navigate to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on Mac).
• Search for 'C# for Visual Studio Code' by Microsoft, click Install.

This extension brings IntelliSense, code navigation, refactoring, and other essential features to your C# development environment in VS Code.

ASP.NET Core Project Structure

ASP.NET Core projects have a specific structure, which helps manage and organize your application's files effectively. Let's explore some key folders and files:

• wwwroot: Contains static files like images and CSS.
• Properties: Contains project-related files like launchSettings.json and launchProfile.json.
• Controllers: Contains the controller classes that handle requests and responses.
• Models: Contains the model classes representing the data structure of your application.
• Startup.cs: The entry point of your application, where you configure middlware, services, and the application's pipeline.
• Program.cs: The starting point of your application, host, and middleware configuration.

Creating an ASP.NET Core Web Application

Now that we've set up VS Code and understand ASP.NET Core's project structure, let's create a simple ASP.NET Core web application. Follow these steps to create a new project:

1. Open VS Code, then open the terminal (View > Terminal or Ctrl+``).

2. Build the following command and press Enter:

dotnet new webapp -n MyWebApp

This command creates a new ASP.NET Core web application named 'MyWebApp'.

Running the ASP.NET Core Web Application

Now that our application is created, let's run it. Follow these steps:

• Navigate into the project folder in the terminal.
• Run the following command and press Enter:

dotnet run

After a few seconds, your application should be running, and you'll see a message displaying the URL to access your web application (http://localhost:5001 by default).

This completes our tutorial on ASP.NET Core and VS Code. You're now equipped to start developing modern, cross-platform web applications using ASP.NET Core and VS Code. So, what's holding you back? Start exploring, experimenting, and building something extraordinary today!
