ASP.NET Core is a cross-platform, high-performance framework launched by Microsoft, designed for C# to develop modern web applications. Its core advantages include: 1. Cross-platform support, which can run on Windows, macOS and Linux, and is compatible with Docker and cloud-native architectures; 2. Modular architecture, which improves performance and flexibility through middleware pipeline loading functions; 3. Built-in dependency injection (DI), supports lifecycle management, and enhances code maintainability and testability; 4. High performance performance, based on Kestrel server, can efficiently handle high concurrent requests under default configuration, suitable for scenarios with limited resources or high response speed requirements.

ASP.NET Core is a cross-platform, high-performance framework launched by Microsoft, designed for building modern web applications using C#. Compared with traditional ASP.NET, it is lighter, more modular, and supports cross-platform operation, making it an ideal choice for developing efficient and scalable web applications.

Cross-platform support: one-time writing, multi-platform deployment

This is one of the most significant advantages of ASP.NET Core. It can run on Windows, macOS, and Linux, which means you can deploy applications flexibly based on your team's technology stack or server environment.

• You can choose a system you are familiar with when developing
• The operating system can be selected according to cost and performance requirements during deployment
• It is very smooth to use with container technologies such as Docker

This is especially important for teams who want to reduce infrastructure dependencies or use cloud-native architectures.

Modular architecture: load on demand, improve performance and flexibility

ASP.NET Core is designed with a middleware pipeline mechanism, where developers can add specific features as needed, instead of loading large amounts of components by default like traditional frameworks.

For example:

• Authentication middleware is only introduced when authentication is required
• If it is an API project, you can choose not to introduce the Razor engine
• You can customize the request processing process to achieve more refined control

This modular structure not only makes applications faster to start, but also makes them easier to maintain and test.

Built-in Dependency Injection (DI): Better code organization and testability

Dependency injection is already standard in modern development, while ASP.NET Core integrates DI containers at the framework level without the need for additional third-party libraries.

• Controllers, services, warehousing, etc. can all be injected through constructors.
• Supports life cycle management (Singleton, Scoped, Transient)
• Easier to unit testing because dependencies are clear and clear

This greatly improves the maintainability and testability of the code, and is particularly suitable for the development of medium and large projects.

High performance: Lightweight engines provide faster response

The underlying layer of ASP.NET Core is Kestrel, a high-performance cross-platform web server. Official data shows that its throughput in some scenarios even exceeds popular frameworks such as Node.js and Ruby.

• High concurrent requests can be handled under default configuration
• Combined with cache mechanism, asynchronous programming model, etc., the performance can be further optimized
• Better control over memory usage and suitable for environments with limited resources

If your application has high requirements for response speed and concurrency capabilities, such as e-commerce platforms, real-time data display, etc., ASP.NET Core is a good choice.

Basically that's it. The advantages of ASP.NET Core are more than these, but what you feel most often in actual development are these aspects: cross-platform, modular, built-in DI and high performance. Use C# to write web applications, and you can basically not make mistakes when choosing this framework.
