➤ How to open, edit and convert ASMX files quickly and easily 🎮

What is an ASMX file?

“ASMX” stands for “Active Server Method File” and refers to a file used for programming in ASP.NET.

An ASMX file can be run by applications that support the ASP.NET programming such as Microsoft Visual Web Developer and Microsoft Visual Studio. Although ASMX files can be run from a .NET Framework-based web server, it is also possible to open ASPX files in PDF, Excel, or Word for code management with a much simpler process.

Categories of an ASMX file

There are two categories of ASMX files: Source and Internet. The former can be opened by text editors such as Notepad ++ or Sublime Text, although it is recommended to use a programming IDE such as Eclipse for Java.

Internet files contain images or text. The most popular ASMX file on the Internet is www. Therefore, it is important that you know what the World Wide Web “www” is and what it serves as a hypertextual document system when managing these kinds of applications and formats.

How to open, edit and convert ASMX files quickly and easily

To open, edit and convert ASMX files, you need to have an application that encodes ASP.NET and perform a procedure that facilitates the conversion as explained below.

Open an AMSX file

To open an ASMX file you can use a text editor such as Notepad, Notepad ++ or any other application of this type. Also, you can open an ASMX file with Visual Studio or from Visual Web Developer which you can get from Microsoft's official website.

Right-click the AMSX file, click “Open With” and select “Choose another application”. A new window will appear with a list of applications to open the file. Locate one of the programs mentioned above or click on “More Applications” and choose the software. Finally, click "OK".

Edit an ASMX file

Edit the ASMX file from a text editor or any other type of free editor. Windows has its own notepad, although it may be limited, luckily you can also replace it with another text editor to add a few lines from the file.

Once the changes have been applied to the ASMX file, click on 'File' and select 'Save As'. Write a name that identifies the file keeping its .asmx format and press the "Save" button.

Convert an ASMX file

If you prefer to convert an ASMX file to another format such as WCF “Windows Communication Foundation”, you need “Visual Studio”. Open this application and in "File" select "New". Then in "Project" choose "Web" and select ASP.NET Web Service Application. Assign a name to the ASMX project and press “Ok”.

Change some elements

Disable comments on the line in Service1.asmx.cs that contains the syntax: System.Web.Script.Services.ScriptService to enable AJAX. Then, in the "Create" menu, select "Create solution" and in "Debug", click "Start without debugging".

Activate the "ASP.NET AJAX" service

On the new web page, select the operation "Bonjour Monde" or "test page". Press the "Invoke" button and you will get an answer in XML. With this message you will confirm the activation of the ASP.NET AJAX service.

Make the conversion

Right click on the ASMX file and select “Add”. Choose "New Item" and then click "AJAX-WCF service enabled". Name the WCF file and press “Add”.

In the file just created and from "Service1.asmx.cs" copy this syntax of the "Hello World" operation (The dots are indicators of each line, they must not be included in the code):

public string HelloWorld () {
"Hello world" returns;
}
Paste the above syntax in the following method:
Blank Audience DoWork () {
// Add your distribution operations
Return;
}

Add the file name

Locate the "Namespace" attribute and add the WCF filename as shown below: Namespace = “file_name”.

Add the “Invoke web” attribute to the “Hello World” operation and set the “Response format” property to return an XML. Then press “Create solution”, open the WCF file and click on “Start without debugging”. This way you can create an equivalence and / or an conversion between ASMX and WCF files.
