SOAP with attachments in VB.NET

I need to use the web service that was provided to me and which uses SOAP with attachments as a means of communication. It also uses WS-Security 1.0 as a form of authentication (the user transmits plain text).

I will work on VB.NET, and my experience with web services is very thin and comes to the creation of a WCF web service by adding a link to the service in another project, thus creating a proxy class and using methods.

I searched the Internet and found that VB.NET does not have native SwA support, is this correct? An example of how I can approach communication, and some indication of where I can better know these concepts will be excellent.

As far as I can tell about this: http://www.w3.org/TR/SOAP-attachments , the attachments should be embedded in the body of the message, which means that you need to combine the answers from Kevin and Tom to build your message.

I noticed that SOAP with attachments seems to be only a representation, not a standard, moreover, it is quite outdated.

Assuming you need to use the web service "as is", I would try to get additional data or examples from the creator / provider of the service, if you can.
