What is a ASPX file
The file extension ASPX are used for automatically or server-generated web pages that lead to an active server. They are commonly associated with the Microsoft ASP.NET framework and can be created using Microsoft's Visual Web Developer program. This website format file can be opened in any web browser if the URL ends with the ASPX extension, i.e. ".aspx".
These files also known as ".NET web forms" may contain VBscript, code written in C#, or XHTML markup. Dynamic code is supported by this web form format as well. The scripts and command contained in the file are processed on a web server which sends the contents to a user's browser in proper HTML format. With the release of ASP.NET Framework 2.0 it is possible to split ASPX files into pages that contain static text only (ASPX) and files that contain the dynamic code (e.g. ASPX.VB).
Here's a small, but not exhaustive list of programs that can open ASPX documents:
- Microsoft Visual Web Developer
- Microsoft Visual Studio 2013
- ES-Computing Edit Plus
- Any Web browser
