Core .NET, also known as .NET Core, is a free, open-source, cross-platform framework developed by Microsoft. It's designed for building modern, scalable, high-performance applications. Here's a brief overview:
Key Features of .NET Core:
Cross-Platform:
- Runs on Windows, mac OS, and Linux.
- Ensures that applications are portable and can run in a variety of environments.
High Performance:
- Known for its performance and scalability.
- Suitable for cloud and micro services architectures.
Unified Platform:
- Supports multiple languages including C#, F#, and VB.NET.
- Can be used for web, desktop, mobile, cloud, gaming, IoT, and AI applications.
Modular and Lightweight:
- Applications can be optimised by including only the necessary libraries.
- Reduces overhead and improves performance.
Open Source:
- Hosted on GitHub, encouraging contributions and collaboration.
- Transparent development process.
Versatile Tooling:
- Rich development environment with Visual Studio, Visual Studio Code, and other IDEs.
- Command-line interface (CLI) tools for managing projects.
Core Components of .NET Core:
ASP.NET Core:
- Framework for building web applications and APIs.
- Provides features like MVC, Razor Pages, SignalR for real-time communication, and Blazor for building interactive web UIs using C#.
