Thanks very much, but I'm afraid it still doesn't work for me.  I'm still getting "Samples is undefined", and Fiddler is telling me:

Parser Error Message: Could not load type 'Microsoft.Web.Services.BridgeRestProxy'.

I've registered .asbx in IIS and added my keys.  I have a feeling that I'm missing some really basic step here, but I don't know what it could be.
