This practical Haskell example encouraged me to install the Visual Studio 2012 trial in order to use F# type providers. However, I am completely stumped as to how to use it to solve that problem. There is an RCSB SOAP web service. I copied an example (which doesn't work because the web service API has changed) using the URL for the WSDL web service from the RCSB:
open Microsoft.FSharp.Data.TypeProviders
type pdb = WsdlService<"http://www.rcsb.org/pdb/services/pdbws?wsdl">
do
let ws = pdb.Getpdbws()
ws.getCurrentPdbIds()
|> printfn "%A"
But this crashes at run-time with the error:
Unhandled Exception: System.InvalidOperationException: RPC Message blastPDBRequest1 in operation blastPDB1 has an invalid body name blastPDB. It must be blastPDB1

Also the SOAP web service is being deprecated in favor of a RESTful one. How might I use that from F# 3.0? What does the simplest working example look like?
