wsdl.exe /o:FileName.vb /n:Namespace.You.Want
http://location.of.wsdl If you run this you'll wind up with a file in your current directory (FileName.vb) that should consist of the entire service representation.
You should then be able to write another vb "class" using the service definitions in FileName.vb, compile with the VB compiler (I think it's vbc) and you'll be good to go.
If you're wanting to use this from a .NET application, I believe that you can create a DLL via vbc with the /target:libary option that you can then register on IIS and go to town.
