What is an ASMX file?

ASMX files mostly belong to ASP.NET by Microsoft. An ASMX file is a script which defines a web service for an ASP.NET-based web application. The ASMX file contains HTML markup with references to related web service discovery scripts, C#, and/or Visual Basic scripts. When a web service script (ASMX file) and its related assemblies are placed in the virtual directory of a server, ASP.NET processes and sends a response from such a service to clients requesting it. Visual Studio integrated development environment is the primary program for creating and editing an ASMX file.

How to open an ASMX file

You need a suitable software like ASP.NET to open an ASMX file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ASMX file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ASMX file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with ASMX files

Associate the ASMX file extension with the correct application.
