any build-in class in .NET to help generate webservice's SOAP client message?

[kelmen]

Greeting,

I have dig through the search, but can't find anything.

I'm exploring Web Service. Manage to get 1 work using VS.NET.

Now I wanna try generate a SOAP message at the client, then send to
my WebSvc. Because the WebSvc client can be developed by anything apart
from .NET, so I wanna know what's the right SOAP msg to form up.

I found sample of how the SOAP msg looks alike. Is this msg supposed
to chunk out manually or is there a class in the .Net for this purpose?

I have no luck trying with the SoapClientMessage, SoapExtension bla
bla bla.

TIA
