Open ASMX File

ASMX files, also known as ASP.NET Web Service files, are primarily associated with the .NET framework. These files contain source code written in a programming language compatible with .NET, often C# or VB.NET, used for creating a web service. This file extension is developed by Microsoft and is utilized to create reusable components that can be used across multiple platforms. Web services using ASMX files could be consumed by clients over HTTP protocol.

Opening and Using ASMX Files

The main tool for working with ASMX files is Microsoft's Visual Studio, a comprehensive development environment that provides the framework and tools needed for building and managing .NET applications. You can open and edit the ASMX file directly, but usually, it makes more sense to open it as part of a solution - i.e., a group of interconnected projects. To open the ASMX file with Visual Studio, simply right-click on the file and select 'Open with' then choose 'Visual Studio.' [visualstudio.microsoft.com]

Uses of ASMX File Extensions

Let's delve into some notable uses of the ASMX file extension.

Building Web Services

Arguably the most significant use of an ASMX file is in building web applications and services. In simplest terms, a web service is a strategy for communication between two devices over a network. It's a software function provided at a network address over the web or the cloud; it is a service that is "always on" as in the concept of 'Software As A Service' (SAAS). [tutorialsteacher.com]

Creating Reusable Components

With the help of ASMX files, programmers can create reusable components to reduce redundancy in their programming projects. These components can be universally accessed and incorporated into other software, ensuring a lower likelihood of duplication and saving significant time for programmers. Als, these components are language independent and can be used across multiple platforms. [msdn.microsoft.com]

ASMX File Important Information

It's worth noting that .NET framework has essentially deprecated ASMX in favor of Windows Communication Foundation (WCF) since .NET 3.0. Hence, while you can still use ASMX in your projects, it's generally recommended to consider more modern alternatives like WCF or ASP.NET Web API if you're starting a new web service project from scratch. And, while ASMX files are primarily connected with web services, they can sometimes be confused with similarly named ASMX.CS or ASMX.VB files. These files are similar but rather than being called by clients to perform operations, they house the underlying code that the ASMX file's web service actually executes. [docs.microsoft.com]

Typical ASMX application file locations:

"g:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /dde
c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe /dde
"C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" /dde

Typical ASMX mime types:

application/xml

Frequently used application names to open ASMX files:

Microsoft Visual Studio 10.0

If a ASMX file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with ASMX file.
If you know the Mac OS application which can work as ASMX file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open ASMX file in it.
If you don't know the application which can open ASMX file then try to search for "ASMX viewer", "application to open ASMX file" or "read ASMX file" queries in the online search engine you like.
Install the application you found and check if it can read ASMX file

How Can I Open ASMX File on Android

If you downloaded a ASMX file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
