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!
