2 Contents Challenges.NET Mobile Architecture Microsoft Mobile Internet Toolkit How.NET Mobile Web Applications Work?? Stand-Alone Windows Applications Emulators Demo Conclusion Questions

3 Challenges Varying Configurations Browser Languages Wireless Network Limitations Pagination & Session Management

4 Varying Configurations Memory - 2MB to 64MB Capabilities - Sound, Color displays Display Area - 128 x 160 to 320 x 480 pixels

5 Browser Languages compact - HTML HTML Wireless Markup Language Handheld Devices Markup Languages VoiceXML

6 Wireless Network Limitations Limited bandwidth - 9.6 Kbps to 11Mbps High latency Intermittent connectivity

7 Additional Challenges Pagination - additional application logic at server side - small pages Vs high latency network Session management - no client side cookies support - additional server side logic

8 .NET Mobile Architecture

9 Microsoft Mobile Internet Toolkit Mobile Web Form Controls - extended versions of web form controls - specific controls Mobile Internet Designer - extends Visual Studio. NET Device Capability Mechanism - machine.config with device specific details

10 Advantages support for variety of devices write-once web pages world-class tool support customizability extensibility

11 How.NET Mobile Applications Work??




15 Stand Alone Mobile Applications Miniature windows desktop applications.NET Compact Framework - CLR implementation Operating Systems that supports.NET CF - Pocket PCs - Windows Mobile 2003 - smartphone 2003

16 Comparison of.NET Compact Framework with.NET Framework CLR for.NET CF is 12% of.NET framework.NET CF supports only VB and C# Data Providers like OleDb, ODBC not supported in.NET CF SqlServerCe data provider for SQL Server 2000 Windows CE provided in.NET CF

17 Comparison of.NET Compact Framework with.NET Framework.NET CF has additional form support with WindowsCE.Forms COM Interop, Enterprise services,.NET Remoting are not supported in.NET CF.NET CF includes Classes for Infrared Data Association and specific device components

18 Benefits of.NET Compact Framework Offline Capabilities Rich User Interface Responsive User Interface Device Support XML and Web services support

19 Emulators Mobile Web Applications - Microsoft Mobile Explorer 3.0 - Ericsson WAP Toolkit 3.1 - Nokia WAP Toolkit 3.1 Stand Alone Mobile Applications - Pocket PC 2002 Emulator - Windows Mobile 2003 Emulator

20 Demo Mobile Web pages with Mobile Explorer 3.0 Mobile windows text editor with Pocket PC 2002 Emulator

21 Conclusion.NET provides excellent support for developing mobile web applications for diverse mobile devices.NET Compact Framework supports development of stand alone windows based applications for high processing power devices.NET abstracts some challenges faced in mobile application development from developer
