ASP.NET Core is a brand new cross-platform web framework BUILT with .NET Core framework.

It is not an update to existing ASP.NET framework. It is a complete rewrite of the ASP.NET framework. It was built from scratch in the effort to make a modular, scalable, super fast, configurable, cross-platform and easily extended web framework.

ASP.NET Core (on Linux!) itself can handle over 2 000 000 – 2 Million requests per second for plaintext request/response scenarios. ASP.NET Core MVC can handle over 1 million requests per second! Compared to Node.js, which can handle about 400 000 requests per second, this is an amazing effort.

It works with both .NET Core and .NET Framework.

ASP.NET Core is much CLEANER and easier to work with. You only need to write 20~30 lines of code and you have the web server ready to run. It also works smoothly with your file system, so can just copy and paste files to your project folder. And no, you don’t need to reference these files from a .csproj file.

Main characterestics of ASP.NET Core:

• DI Container which is quite SIMPLE and built-in. You can extend it with other popular DI containers
• Built-in and extensible structured logging. You can redirect output to as many sources as you want (file, Azure, AWS, console)
• Extensible strongly TYPED configuration, which can also be used to reload at run-time
• Kestrel – new, cross-platform and super fast web server which can stand alone without IIS, Nginx or Apache
• New, fully async pipeline. It is easily configured via middleware
• ASP.NET All meta package which improves development speed, and enables you to reference all Microsoft packages for ASP.NET Core and it will deploy only those that are being used by your code
• There is no web.config. We now use appsettings.json file in combination with other sources of configuration (command line args, environment variables, etc.)
• There is no Global.asax – We have Startup.cs which is used to set up Middleware and services for DI Container.
