3. What is.NET Compact Framework?.NET Framework. NET Compact Framework

4. What is.NET Compact Framework?  Lightweight version of.NET Framework  Designed for resource-constrained devices  Compatible with VS.NET, C#, VB.NET  Runs applications securely on-device  High performance JIT compiler

5. What is.NET Compact Framework?  Guarantees robustness and security  Highly interactive, offline, and networked experiences  Makes it easy to consume web services  Tunable size and performance

6. Calculator Application Sample using.NET CF

7. .NET CF – Design Goals  Small CLR for Devices  Leverage VS to design, develop & debug  Web Service Access on Devices  Run seamlessly with the OS on the devices  Single binary deployment for all Pocket PC and Windows CE.NET CPUs  Enhanced developer productivity using.NET Compact Framework and Visual Studio.NET

10. .NET CLR Common Features  Verifiable type safe execution  No uninitialized variables, unsafe casts, bad array indexing, bad pointer math  Garbage Collection  No ref-counting, no leaks  JIT compilation  Error handling with exceptions  Common type system  Call, inherit, and source-level debug across different languages

11. Compact CLR Differences  COM Interop  Good support for calling native DLLs  Support for calling a COM object through DLL wrappers  No support for writing a COM / ActiveX object  No Install-time JIT (nGen) / No Reflection Emit  No Remoting / Client web services is fully supported  No Generic Serialization  Datasets can be serialized to XML  Subsets of other areas of functionality

12. Developing Games for Smart Device App using.NET CF

13. .NET Framework CLR Size  Framework size (RAM or ROM)  ~1.5 MB  Running RAM needs  1 MB+ (depends on app)  Typical application sizes  5 - 100 KB  Apps often smaller due to use of platform features in the framework

14. .NET Compact Framework - Features  Base Classes  Data/XML  XML Web Service Client  Threading  Native Code Interop  Globalization  Windows Forms Support

15. Mobile Controls for ASP.NET  Write-once mobile web pages  From a single code base target multiple devices  Support for a variety of devices  Web enabled Cell Phones, PDAs and Pagers  Support multiple mark-up languages  WML1.1 (WAP); cHTML 1.0, HTML, XHTML  Customizable and extensible framework  Add new controls and support for new devices  Integrates with Visual Studio.NET  World-class development tool

16. Power Toys for.NET CF  Remote Performance Monitor and GC Heap Viewer .NET CF CLR Profiler  App Configuration Tool (NetCFcfg.exe) .NET CF ServiceModel Metadata Tool  Remote Logging Configuration Tool .NET CF Network Log Viewer
