Specified method is not supported

Description

Standard WMI interface works, but the type provider does not.

Repro steps

Given this code:

let test () =
    type Local = WmiProvider<"localhost">
    let wmi = Local.GetDataContext ()
    for e in wmi.Win32_PnPEntity do
        printfn "%s" e.Caption

At design time, there is no error and Intellisense works properly (Caption shows up in the suggestion list), however at compile time, there is this error:

Unexpected exception from provided type 'FSharp.Management.WmiProvider,MachineName="localhost"+ServiceTypes+Win32_PnPEntity' member 'GetMethods': The type provider 'FSharp.Management.DesignTime.WmiExtender' reported an error: Specified method is not supported.

However this works, if I use the low-level WMI interface:

let srch = new ManagementObjectSearcher ("SELECT * FROM WIN32_PnPEntity")
// etc...

As expected, the Captions are printed.
