What Is ASP.NET?
ASP.NET is an open-source, server-side web application framework developed by Microsoft. It is used to build dynamic websites, web apps, and APIs using the .NET platform. ASP.NET allows developers to write code in languages like C# or VB.NET, and it runs on Windows, Linux, and macOS via .NET Core or the modern ASP.NET Core version.
With built-in support for MVC architecture, Razor pages, Web APIs, and real-time applications (SignalR), ASP.NET provides a powerful, secure, and high-performance environment for developing enterprise-grade web applications.
