DFS Delete - Samples do not match API

qzc21f

So paraphasing a sample I see this:

DeleteProfile deleteProfile = new DeleteProfile(); 

deleteProfile.IsDeepDeleteFolders = true; 

deleteProfile.IsDeepDeleteChildrenInFolders = true; 

OperationOptions operationOptions = new OperationOptions(); 

operationOptions.DeleteProfile = deleteProfile; 

objectService.Delete(objectIdSet, operationOptions); 

But when I look in c# as the OperationOptions object I se not see a "DeleteProfile" property, only a Profiles Array.  Is this the documentation being out of date or something else?
