.NET CF 2.0 Overview What is it? Why .NET CF? What’s Needed? What can you develop for? What’s New in CF 2.0? What’s Missing in CF 2.0?

.NET CF - What is it? First made it’s debut in 2002/2003 Developed to bring the managed developer to the mobile space Developed to have the same namespaces as the full framework Has device specific classes and controls Windows Mobile 5.0 API adds more classes

Why .NET CF? If you are a .NET shop then why not? If you are an ISV, why not port your application to potentially 107million users If you are an enterprise, why not extend some highly used or mission critical desktop application

What’s Needed? If you have developed for the desktop then you already know how to develop for a mobile device Visual Studio 2005 Standard Edition - Includes CF1.0 and CF2.0 C# or VB.Net development experience. Can also use native C++ SDKs – some available with VS2005 some available for download A real device to test on A consumer or enterprise focused idea!

What Can you develop for?

What’s new in CF2.0 Command line compile COM Interop Resource files same as the desktop VB My Objects (My.Resources, My.Webservices, My.Forms) System.Xml enhancements (XPath, XmlSerializer, Schema) Improved threading SQL Mobile replaces SQL CE 2.0 MSMQ now available Framework 2.0 changes Partial Classes Generics Anonymous Methods

What’s Missing in CF 2.0? My Objects My.Applications My.Computer My.User My.Settings Xml Schema validation is not supported because of size Timers – Start()/Stop() are not supported Remoting is not supported Sockets – not everything is supported Reflection does not have Emit namespace Activated/Deactivated events are not supported, can use GotFocus()/LostFocus() instead Various controls because not available on Windows Mobile
