ASP.NET Core Performance Benchmarks
ASP.NET Core is the fastest framework which can serve 2300% more requests per second as compared to ASP.NET 4.6. It's around 20 times faster than Node.js.
ASP.NET Core Anatomy
In ASP.NET Core everything starts with Program.cs, Main Method. ASP.NET Core apps require a startup class which serves as an alternative to Global.asax in ASP.NET 4.x. It uses a cross-platform Kestrel web server to serve the request and response. Here, IIS/Apache Tomcat/Nginx works as a delegation web server, and is used to delegate the incoming request to the internal Kestrel web server.
Differences Between ASP.NET Framework and .NET Core
.NET Core is a general-purpose development platform, while ASP.NET Core is a framework for building web applications on top of .NET Core.

Why ASP.NET Core/Benefits of ASP.NET Core?
- Open Source: The entire source code for this .NET Core Framework is available at https://github.com/aspnet, and you can download it.
- Cross-Platform: ASP.NET Core applications can be developed and run on different platforms such as Windows, Mac, or Linux Operating Systems. You can use either Visual Studio or Visual Studio Code or any third-party editor such as ATOM, Sublime, etc. for developing ASP.NET Core applications.
- Unified MVC and Web API Framework: A single controller class can be used to handle both. The Controller in ASP.NET Core (either Web APPs or Web APIs) application will inherit from the Controller base class and return the IActionResult interface.
- Testing and Maintainability: Applications developed using the ASP.NET Core MVC framework can easily be tested and maintained as you can separate different parts of your application into independent pieces and test them independently.
- Excellent developer tools: ASP.NET Core comes with a lot of preloaded tools like Libmam, ReSharper, etc.
What ASP.NET Core doesn't have :
- Global.asax
- Web.Config
- Modules and Handlers
- Typical ASP.NET page life-cycle
