Create nodes with C#

Hello all,

I've been through the documentation, but I don't see any examples for using the WSDL for creating a node in vb.net or C#.  I've looked through the JAVA example and re-created in C# as far as I can see, but when I try to call client.create("Orion.Nodes", PropertBag") I get the following exception:

System.ServiceModel.CommunicationException was unhandled

  HResult=-2146233087

  Message=There was an error while trying to serialize parameter http://schemas.solarwinds.com/2007/08/informationservice:properties. The InnerException message was 'Member type in type SolarwindsAPI.SWClient.item cannot be serialized. This exception is usually caused by trying to use a null value where a null value is not allowed. The 'type' member is set to its default value (usually null or zero). The member's EmitDefault setting is 'false', indicating that the member should not be serialized. However, the member's IsRequired setting is 'true', indicating that it must be serialized. This conflict cannot be resolved.  Consider setting 'type' to a non-default value. Alternatively, you can change the EmitDefaultValue property on the DataMemberAttribute attribute to true, or changing the IsRequired property to false.'.  Please see InnerException for more details.

I notice that in java, there is a nodeProps.getAsSoapPropertyBag, however, this does not exist in the WSDL client?  Is this still an issue?
