| Most of the common functionality found in the desktop Framework is also provided by the Compact Framework. This list shows some of the common namespaces available, though it is not comprehensive. Most namespaces contain the same classes you are used to.
| For example, with File IO, you can continue to use the File and Directory classes. With networking, you can continue to work directly with Sockets. Some namespaces, like XML and Threading, provide the same basic functionality, but some features have been omitted in the interest of reducing the footprint of the assembly. For example, the XML namespace has no support for queries with XPath or transformations with XSLT. Also, while you can create and manage Threads, you can not asynchronously invoke delegates.
