.Net Compact Framework A Mostly Straight Path, but with Some Interesting Curves Richard Kucia Kucia Associates

Agenda What is the.Net Compact Framework? Developing in a Compact World Inclusions and Exclusions Examples

What is the.Net CF? Target: Mobile Devices The Same Framework – but optimized Integrated into VS.Net 2003 Formerly: Smart Device Extensions

.NET CF Design Goals Portable and small.NET CLR for devices –Enable Visual Basic® and C# Leverage Visual Studio®.NET –Run managed.EXEs and.DLLs directly –Debug with Visual Studio.NET Enable rich client Web Services and line of business applications on devices –Class libs for forms, drawing, storage, net, data access, XML Peacefully co-exist with host OS –Run on native threads, P/Invoke to call native code

Target: Mobile Devices Compaq, HP, Dell, Toshiba, … PocketPC 2000, 2002 Windows Mobile (aka PPC 2003) –.Net CF in ROM! Windows CE SmartPhone No Palm/Handspring

Target: Mobile Devices Developer Productivity Implications TechnicalBusiness Familiar dev experience… same tools and process Different approach to application design, but core development skills transfer Technical benefits of platform and tools yield productivity boost Desktop training on.NET is fully applicable to smart devices Desktop developers can now target devices with low incremental cost.NET developer productivity gains apply to smart devices as they do to the desktop and server

The Framework – Optimized 20mb 1.5mb True subset – no breaking changes Same languages, same code, same MSIL Multiple target CPUs

How Rich is the Working Environment? CLRJIT Garbage Collection Type safety; exceptions Threading Windows OS (PInvoke) SQL Server CE including replication ActiveSync Remote Viewer Web Services Sockets/StreamsADO.NetGraphics
