What is the difference between ASP.NET and ASP.NET Core

ASP.NET and ASP.NET Core are both web application frameworks developed by Microsoft.

ASP.NET:

Released: 2002

Focus: Primarily for web development

Platform: Windows (limited Linux support through Mono)

License: Proprietary (closed-source)

Based on: .NET Framework.

Key Features:

Web Forms: Provides a drag-and-drop, event-driven model for building web applications.

MVC: Model-View-Controller framework for building scalable and testable web applications.

Web API: Framework for building HTTP services that can be consumed by various clients including browsers, mobile devices, and tablets.

SignalR: Library for adding real-time web functionality to applications.

Limitations:

Platform Dependency: Only runs on Windows.

ASP.NET Core:

Released: 2016

Focus: General-purpose web development and cloud applications

Platform: Cross-platform (Windows, macOS, Linux)

License: Open-source

Based on: .NET Core

Limitations:

Platform Independence: Cross-platform, runs on Windows, macOS, and Linux.

Key Differences:

Platform: ASP.NET Core's biggest advantage is its cross-platform compatibility, allowing development on various operating systems. ASP.NET is primarily Windows-focused.

Open-Source: ASP.NET Core is open-source, encouraging community contributions and faster development cycles. ASP.NET is proprietary.

Modern Architecture: ASP.NET Core boasts a modular and lightweight architecture, leading to improved performance and scalability.

Dependency Injection: ASP.NET Core offers a more robust dependency injection system for easier component management.

ASP.NET Core was introduced primarily to address the limitations of the original ASP.NET framework and to adapt to the evolving landscape of software development.

Cross-platform compatibility: The original ASP.NET was primarily tied to Windows. .NET Core was designed to run on Windows, macOS, and Linux, expanding its reach and appeal to a wider developer community.

Performance improvements: .NET Core was built from the ground up with performance in mind. It offers significant performance enhancements compared to its predecessor.

Open-source development: By adopting an open-source model, .NET Core fostered community involvement, accelerated development, and increased transparency.

Cloud-native development: The rise of cloud computing necessitated a framework that was optimized for cloud environments. .NET Core was designed with cloud-native development in mind.

Modular architecture: .NET Core adopted a modular architecture, allowing developers to include only the necessary components, resulting in smaller and more efficient applications.

Improved developer experience: .NET Core introduced a streamlined development experience with features like dependency injection, configuration, and logging.
