Hi,

I'm using code that was generated by the addition of a Web Reference WSDL file
(i.e.: http://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl).

When invoking a certain method, the runtime tries to deserialize a reply from a
remote web service server and fails with an System.InvalidOperationException
exception. The message is "There was an error reflecting type '...'", which
originated from a XmlAnyElementAttribute that isn't understood:

System.InvalidOperationException: The element Any has been attributed with an
XmlAnyElementAttribute and a namespace 'http://www.onvif.org/ver10/schema', but
no name. When a namespace is supplied, a name is also required. Supply a name
or remove the namespace.

Effectively, the declaration is as follows:

  [System.Xml.Serialization.XmlAnyElementAttribute(Namespace =
"http://www.onvif.org/ver10/schema", Order = 0)]
  public System.Xml.XmlElement[] Any {
    ...
  }

I checked with the generated code when using Microsoft VS 2008, and it's the
same: The 'Namespace' value is specified, but not the 'Name' value. The runtime
should be able to cope with the generated code.


Reproducible: Always

Steps to Reproduce:
1. Generate the code from the web reference at
http://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl
2. Instantiate a DeviceClient object with an HTTP binding and an endpoint.
3. Invoke the 'GetNetworkInterfaces' function.
4. Deserialization of reply will fail.
Actual Results:  
-> System.InvalidOperationException: There was an error reflecting type
'onvif_proto.ONVIFDeviceManagement.NetworkInterface'.
---> System.InvalidOperationException: There was an error reflecting field
'Extension'. 
---> System.InvalidOperationException: There was an error reflecting type
'onvif_proto.ONVIFDeviceManagement.NetworkInterfaceExtension'. 
---> System.InvalidOperationException: There was an error reflecting field
'Extension'. 
---> System.InvalidOperationException: There was an error reflecting type
'onvif_proto.ONVIFDeviceManagement.NetworkInterfaceExtension2'.
---> System.InvalidOperationException: There was an error reflecting field
'Any'. 
---> System.InvalidOperationException: The element Any has been attributed with
an XmlAnyElementAttribute and a namespace 'http://www.onvif.org/ver10/schema',
but no name. When a namespace is supplied, a name is also required. Supply a
name or remove the namespace.

Expected Results:  
Reply is correctly deserialized.

For now I can fix it by adding the 'Name="Any"' value to the
XmlAnyElementAttribute.
