13 Building Websites Using ASP.NET Core

This chapter is about building websites with a modern HTTP architecture on the server side using ASP.NET Core.

ASP.NET Core is a free, open-source, and cross-platform web framework developed by Microsoft for building modern, cloud-based, and internet-connected applications. It is a significant redesign of the previous ASP.NET framework, focusing on flexibility, modularity, and performance.

ASP.NET Core provides a unified programming model for building web user interface (UI) and web APIs, which means you can use the same framework for both server-side and client-side logic.

ASP.NET Core is optimized for high performance and can handle a significant number of requests per second. It has a lightweight, modular ...
