What is ASP.NET?

ASP.NET is a development framework used to build web applications and services. Developed and maintained by Microsoft, it is specifically designed for use on the Windows operating system. Built on the .NET framework, ASP.NET utilizes a model called ASP.NET Web Forms to create dynamic and interactive web applications. It also includes other features such as the ASP.NET MVC (Model-View-Controller) pattern for building layered web applications, as well as ASP.NET Web API for creating and delivering HTTP-based services. Written in programming languages like C# or Visual Basic, ASP.NET provides a variety of tools and libraries to streamline the web development process.
