Agenda
  • Introduction
  • A Brief History of Windows Mobile Development
  • Introduction to .NET Compact Framework
    Development
  • .NET CF Tips, Tricks and Recommendations
  • .NET CF Futures
  • Q A

3
Introduction
  • Windows Mobile Evangelist
  • Consumer
  • Enterprise
  • Developer
  • Developer
  • Enterprise focus
  • Multiple languages, platforms and technologies

4
A Brief History of Windows Mobile Development
  • Embedded Tools for Visual Studio
  • VS 6
  • Tools for VB, C
  • eMBedded Tools
  • Standalone and free
  • eVB
  • eC
  • .NET Compact Framework (First Pass)
  • Visual Studio.NET
  • Smart Device Extensions

5
Current State of the .NET Compact Framework
  • Visual Studio.NET 2003
  • Smart Device Projects
  • .NET Compact Framework 1.1

6
Introduction to the .NET Compact Framework
  • What is the .NET CF?
  • What can I do with the .NET CF?
  • What cant I do with the .NET CF?

7
What is the .NET CF?
  • Essentially, the .NET CF is an extended subset
    of the .NET Framework
  • Subset Some non-essential classes are not
    included
  • Extended Functionality specific to the Windows
    Mobile platform
  • High-level goal Extend the .NET developer
    platform to the Windows Mobile device platform

8
What can I do with the .NET CF?
  • Simple answer
  • Much of what you would do with regards to .NET
    client development
  • Possibilities
  • Rich client applications
  • Web services
  • Extending enterprise applications to Windows
    Mobile devices

9
What cant I do with the .NET CF?
  • Simple answer Not much
  • Limitations are mostly restricted to the classes
    not included in the .NET CF
  • .NET Remoting
  • Web server/ASP.NET
  • Some of the limitations can be overcome by
    third-party supplements
  • More on that later

10
DEMO VS.NET / .NET CF Development
11
.NET CF Tips, Tricks and Recommendations
  • Fill In The Holes
  • UI Design Considerations
  • Extending Enterprise Applications

12
Fill In The Holes
  • Notable gaps in the .NET CF
  • Managed access to Pocket Outlook
  • XML Serialization
  • Managed access to platform APIs
  • Third-Party Tools can fill the gap

13
OpenNETCF.org Smart Device Framework
  • Open source .NET CF library
  • Designed to fill the gaps in the .NET CF
  • http//www.opennetcf.org

14
DEMO Smart Device Framework
15
Pocket Outlook In-The-Hand
  • Managed access to Pocket Outlook
  • Contacts
  • Tasks
  • Appointments

16
DEMO Pocket Outlook In-The-Hand
17
Pocket PC Magazine Best Software Awards
  • Includes a Developer category
  • Dozens of third-party tools for .NET CF
    development

18
UI Design Considerations
  • UI Usability
  • Performance

19
UI Usability
  • Three device categories within the Windows Mobile
    platform
  • Windows Mobile for Pocket PC
  • Windows Mobile for Pocket PC Phone Edition
  • Windows Mobile for Smartphone
  • Smartphone does not support stylus entry
  • T9 input and key navigation
  • IMPACT Screen layouts for Smartphone should be
    carefully considered
  • Tab Order

20
UI Usability
  • Windows Mobile 2003 Second Edition
  • Supports
  • Landscape and portrait orientations
  • HiDPI resolution (VGA)
  • IMPACT Applications should be orientation- and
    resolution-aware
  • For more information
  • MSDN Mobile and Embedded Developer Center
  • http//msdn.microsoft.com/mobility
  • ARTICLE Developing Orientation and dpi Aware
    Applications for the .NET Compact Framework
  • http//msdn.microsoft.com/library/default.asp?url
    /library/en-us/dnwm2k3/html/dpi_awareness.asp

21
DEMO Orientation-Awareness
22
UI Usability
  • Limited Screen Real Estate
  • Pocket PC, Phone Edition
  • VGA 480 x 640
  • QVGA (Most Common) 240 x 320
  • Smartphone (Smaller Screen)
  • VGA 480 x 640
  • QVGA (Most Common) 240 x 320
  • IMPACT UIs should be designed and tested for
    usability
  • Analogy Early days of GUI and web application
    development

23
Performance
  • Windows Mobile Architecture Primer
  • Performance Techniques

24
Windows Mobile Architecture
  • CPUs
  • Memory

25
Device CPUs
  • Intel XScale
  • Designed for battery life (ULV)
  • Fastest production model 624 MHz
  • TI OMAP
  • Designed for use in Phone Edition and Smartphone
  • Even more emphasis on battery life
  • 200 MHz
  • Samsung Mobile CPU
  • Multiple clock speeds fastest 533 MHz

26
Device CPUs
  • All are ARM Instruction Set compatible
  • You do not have to worry about device CPU
    differences
  • OVERALL IMPACTS
  • CPUs are not as powerful as desktop computers
  • Processor-intensive applications will run more
    slowly
  • Consider offloading heavy lifting
  • Web services/Server

27
Memory Model
  • Non-volatile ROM
  • System ROM
  • FileStore
  • Data will persist beyond a hard reset
  • Volatile ROM
  • Main Memory
  • Data will not persist beyond a hard reset
  • Smartphone OS
  • Volatile ROM will not persist beyond a soft reset

28
Memory Management
  • Volatile ROM is broken into two categories
  • Storage Memory Application and data stored in
    the file system
  • Program Memory Memory space for running
    applications
  • Virtual RAM
  • The more that is stored in Storage Memory, the
    less that is available for Program Memory
  • IMPACT Memory can be constrained. Applications
    should be designed for maximum memory management.

29
Performance Tips
  • UI Usability
  • Memory Management/Performance

30
UI Usability
  • Avoid graphics-intensive screens
  • Real Estate
  • Processing
  • Consider tabs rather than multiple forms
  • There is an initial performance hit
  • Less need for opening multiple forms
  • Preloading of forms
  • There is an initial performance hit
  • Showing rather than initializing saves time
    during execution

31
DEMO UI Usability
32
Memory Management
  • When done with objects, dispose of them
  • Do not rely solely on garbage collection
  • When connecting via the network, connect only as
    long as you need to
  • For enterprise and Internet applications Plan
    for an occasionally connected model of data
    management
  • There is no perfect wireless technology
  • Consider
  • SQL Server CE
  • XML

33
SQL Server CE
  • Limited subset of SQL Server functionality
  • Good for
  • Persistent storage locally
  • Persistent storage for occasionally-connected
    applications and large sets of data
  • Merge Replication
  • Currently, SQL Server CE requires an additional
    installation

34
XML
  • Good for
  • Persistent storage of smaller sets of data
  • Local storage
  • Occasionally-connected computing
  • Not as secure as SQL Server CE

35
.NET CF Futures
  • Whidbey Visual Studio.NET 2005
  • .NET Compact Framework 2.0

36
Visual Studio.NET 2005
  • New Packaging
  • Express versions Will not include .NET CF
    development
  • Professional version will provide .NET CF
    support
  • Native Emulators
  • Previously, an x86 emulator ran on the desktop
  • Integrated support for landscape development
  • Complete deployment support
  • Installation wizard support for Windows Mobile

37
.NET Compact Framework 2.0
  • Additional classes
  • Serialization
  • Event Notification API
  • Publish/Subscribe methodology
  • Applications can subscribe to a variety of system
    events
  • Applications can publish events
  • POSSIBLE USES
  • SMS Interception
  • Device-side real-time application integration
