ASP.NET Core
A high-performance, cross-platform, open-source framework by Microsoft for building modern, cloud-connected web applications and scalable APIs.
About ASP.NET Core
ASP.NET Core is a complete redesign of the historic ASP.NET framework. Engineered by Microsoft, it is an open-source, cross-platform framework that allows developers to build high-performance web applications, IoT apps, and robust backend APIs that run seamlessly on Windows, macOS, and Linux.
Unlike the older ASP.NET framework that was deeply tied to Windows IIS servers, ASP.NET Core is incredibly modular and lightweight. It unifies the MVC and Web API architectures into a single, cohesive programming model. Leveraging the massive performance improvements of modern .NET, it consistently ranks among the fastest web frameworks in independent industry benchmarks.
It features robust, built-in dependency injection, tight integration with Entity Framework Core (an advanced ORM), and out-of-the-box support for real-time web functionality via SignalR. ASP.NET Core provides the ultimate enterprise foundation for teams deeply integrated into the Microsoft and Azure ecosystems.
Key Features
- Cross-Platform Support: Develop and run applications seamlessly across Windows, macOS, and Linux environments.
- Unified MVC Architecture: Combines web UI (Model-View-Controller) and Web API architectures into a single, cohesive programming paradigm.
- High Performance: Heavily optimized runtime that frequently tops industry benchmarks for server response times and throughput.
- Built-in Dependency Injection: Natively supports dependency injection to promote modular, highly testable, and maintainable codebases.
- SignalR for Real-Time: Built-in capabilities to easily add real-time bidirectional communication (WebSockets) to applications.
Pricing
Free and open source. No framework licensing fees, including for commercial use.

FAQ
What is ASP.NET Core used for?
ASP.NET Core is a framework for building web applications, backend services, REST APIs, and real-time applications with .NET. It supports development approaches including MVC, Razor Pages, Minimal APIs, and SignalR.
Is ASP.NET Core free for commercial use?
Yes. ASP.NET Core is open source under the MIT License and has no framework licensing fees, including for commercial use. Hosting, infrastructure, optional paid development tools, and commercial support may involve separate costs.
Do I need Windows or Microsoft Azure to use ASP.NET Core?
No. ASP.NET Core supports Windows, Linux, and macOS. Applications can run on your own servers or compatible hosting platforms. Microsoft Azure is an optional deployment choice.
Can ASP.NET Core build REST APIs?
Yes. ASP.NET Core supports REST API development using controllers or Minimal APIs. Controllers provide an organized approach using controller classes, while Minimal APIs let developers define HTTP endpoints with less setup code.
Does ASP.NET Core support authentication and authorization?
Yes. ASP.NET Core includes authentication and authorization capabilities, along with data protection features. Developers must configure these components to match their application's identity providers, access rules, and security requirements.
How does ASP.NET Core support real-time applications?
ASP.NET Core provides SignalR for features such as live dashboards, chat, notifications, and collaborative applications. SignalR uses WebSockets when available and supports Server-Sent Events and long polling as fallback transports.
What is Entity Framework Core, and is it required?
Entity Framework Core is a separate, open-source object-relational mapper that lets .NET applications query and save database information using .NET objects. It integrates with ASP.NET Core but is optional; applications can use other data-access approaches.
Does ASP.NET Core include dependency injection?
Yes. ASP.NET Core includes built-in dependency injection for registering services and providing them to application components. This helps developers manage dependencies and replace implementations when configuring or testing an application.
