ASP.NET Core Web Development

Master the latest in web application development with Microsoft's powerful framework.

Getting Started with ASP.NET Core

Welcome to the world of ASP.NET Core! This tutorial series will guide you through building modern, cross-platform, and high-performance web applications.

What is ASP.NET Core?

ASP.NET Core is an open-source, cross-platform framework for building modern, cloud-based, internet-connected applications. It's a rewrite of ASP.NET 4.x, designed for performance and modularity. You can develop applications using C#, F#, or Visual Basic.

Key Benefits:

  • Cross-Platform: Run your applications on Windows, macOS, and Linux.
  • High Performance: Optimized for speed and efficiency.
  • Modular Design: Lightweight and extensible, allowing you to include only what you need.
  • Unified Story: ASP.NET Core supports building both web UI (like MVC and Razor Pages) and web APIs in a single project.
  • Open Source: Developed and maintained by Microsoft and the community.

Prerequisites

Before you begin, ensure you have the following installed:

  • .NET SDK: Download and install the latest .NET SDK from the official .NET website.
  • Code Editor: Visual Studio Code is highly recommended, but Visual Studio or JetBrains Rider are also excellent choices.

Creating Your First ASP.NET Core Application

Let's create a simple "Hello, World!" web application using the .NET CLI.

  1. Open your terminal or command prompt.

  2. Create a new directory for your project and navigate into it:

    mkdir MyWebApp
cd MyWebApp

  3. Create a new ASP.NET Core Web App project:

    dotnet new webapp

    This command creates a new project with a Razor Pages structure.

  4. Run the application:

    dotnet run

  5. Open your web browser and navigate to the URL provided in the output (usually https://localhost:5001 or http://localhost:5000).
