| There are several namespaces that are missing completely from the Compact Framework. This list shows many of the namespaces that are either omitted entirely or have significantly reduced functionality.
| For example, ASP.NET is not supported on Smart Devices, so you can not host Web applications or Web Services.
| The System.Configuration namespace has no support for configuration files, so you will need to create your own mechanism for persisting application and user settings.
| When working with XML, you have full DOM support, but no XPath support, so you can only navigate XML documents through explicit node referencing. There is also no support for serialization, either through the XML.Serialization namespace or by using XML or Binary serializers from the Serialization namespace. Serialization is supported for DataSets and for invoking Web Services, but there is no support for serializing your own objects.
