About ASPX Files
An .aspx file is a webpage written in the Active Server Page Extended (ASPX) format, which is part of the ASP.NET framework. It is designed to be processed on a server where it executes the embedded code and delivers the final output, typically as plain HTML—to the user's browser. The .aspx file may contain a mix of HTML, CSS, JavaScript, and server-side code written in languages like C# or VB.NET.
Microsoft introduced the ASP.NET framework, including .aspx files, in 2002 as part of its .NET platform. ASP.NET allows developers to build feature-rich web applications with server-side capabilities, such as handling user authentication, managing databases, or generating personalized content. For example, enterprise environments widely use .aspx files for web portals, e-commerce platforms, and business applications.
Developers typically use web app development programs to view and edit .aspx files. However, they may also use source code editors and plain text editors, although text editors don't provide the same helpful editing features that web app development programs and source code editors offer.
