ASP.NET Core Framework Overview

Welcome to the official documentation for ASP.NET Core, Microsoft's open-source, cross-platform framework for building modern, cloud-based, internet-connected applications.

ASP.NET Core is a rewrite of ASP.NET that addresses many of the shortcomings of previous versions and provides a more modular, performant, and flexible platform. It's designed to run on Windows, macOS, and Linux.

Key Features and Benefits

• Cross-Platform: Develop and run applications on Windows, macOS, and Linux.
• High Performance: Built from the ground up for speed and efficiency, making it one of the fastest web frameworks available.
• Unified MVC and Web API: A single programming model for building both web UI and web APIs.
• Modern Architecture: Leverages modern design patterns like Dependency Injection and Middleware for greater flexibility.
• Open Source: Active community development and transparency.
• Cloud-Ready: Optimized for microservices, containerization (Docker), and cloud deployment.
• Tag Helpers: A more convenient, HTML-like syntax for server-side code in Razor files.
• Blazor: Enables client-side C# development with a component-based architecture.

Core Project Types

ASP.NET Core supports various project templates to suit different application needs:

Web Applications

Build dynamic websites and web applications using the Model-View-Controller (MVC) pattern or Razor Pages for simpler page-focused scenarios.

Web APIs

Create HTTP services that can be consumed by a wide range of clients, including single-page applications (SPAs), mobile apps, and other backend services.

Blazor Applications

Develop interactive client-side web UIs with C# instead of JavaScript. Blazor allows you to build rich, real-time user experiences.

gRPC Services

Build high-performance, efficient, and modern RPC (Remote Procedure Call) services.
