ASP.NET
Also written: ASP.NET Core
ASP.NET is a Microsoft web framework for building modern web apps and services.
ASP.NET is a set of technologies from Microsoft used to build websites and web applications. Think of it like a toolkit that helps developers create the parts of a website that run on the server, handling things like user logins, database interactions, and displaying dynamic content.
For example, when you log into a website, ASP.NET might be the technology that checks your username and password against a database and then sends back the correct page for you to see. It's a foundational tool for many web experiences you use daily.
ASP.NET is an open-source, server-side web application framework developed by Microsoft. It allows developers to build dynamic websites, web applications, and web services using languages like C# or F#. It supports various architectural patterns, including Model-View-Controller (MVC) and Razor Pages, enabling the creation of scalable and maintainable web solutions.
Key components include the ASP.NET Core runtime, which is cross-platform and high-performance, and libraries for handling HTTP requests, routing, authentication, and data access. Its extensibility and integration with the .NET ecosystem make it a popular choice for enterprise-level web development.
Microsoft's open-sourcing of technologies like .NET, alongside TypeScript and VS Code, is highlighted as a key part of its current AI strategy. This move connects its developer tools and platforms to its AI advancements, including Copilot.

- Microsoft Copilot
- Microsoft Copilot leverages .NET as a foundational technology for building and integrating AI-powered applications and services, reflecting Microsoft's broader commitment to open-source development.
ASP.NET was first released by Microsoft in early 2002 as part of the .NET framework. It was a significant evolution from earlier Microsoft web technologies like ASP (Active Server Pages). Source ↗
