In this session you will learn:•The .NET Framework Architecture.•What is a .NET Compact Framework program.•How to build the User Interface for Mobile Applications.•How to manage device data.•To develop a simple mobile application.

Visual Basic 2005

OverviewOverview

The .NET Compact Framework is a programming interface and runtime library created at the nexus of two Microsoft technologies:◦Windows CE, an operating system for mobile

and embedded smart devices◦.NET, Microsoft's reinvention of its

programming interfaces and developer tools

OverviewOverview

The .NET Compact Framework uses some of the same class libraries as the full .NET Framework and also a few libraries designed specifically for mobile devices such as Windows CE InputPanel

To be able to run applications powered by the .NET Compact Framework, the platform must support the Microsoft .NET Compact Framework runtime
