Convert a file to ASMX

To convert other file formats to the "Web Service Source" file type, you need software like Visual_Studio or a similar tool.

About ASMX files

The .ASMX file extension represents an ASP.NET Web Service source file, a legacy format used by Microsoft .NET Framework to build SOAP-based APIs. These files contain the logic - written in C# or VB.NET - that allows different applications to communicate over the internet.

Common Problem: Users often encounter .ASMX files on their local computer by mistake. If a web server is misconfigured, it may force your browser to download the .ASMX file instead of running it. Because these are server-side scripts requiring IIS (Internet Information Services) to execute, you cannot simply "open" them like a Word document or run them like an application. They are useless without the supporting server environment.

Best Conversion Targets:

For Code Review: Convert .ASMX to TXT or CS/VB to view the underlying source code in any text editor.
For Documentation: Convert the text content to PDF or DOCX to archive the API logic or share it with developers without sending raw code files.
For Integration: While you cannot directly convert a local .ASMX file to WSDL, you can generate the WSDL (Web Service Description Language) by hosting the file and appending ?wsdl to the URL, or by using the Visual Studio command-line tool wsdl.exe to generate proxy classes.

Convert.Guru analyzes your ASMX file, detects the exact format, and lets you read the text inside.

Users also converted ASHX, ASPX, AXD, WCF and WSDL files.
