Agenda Introduction Mobile Platform .Net Compact Framework Demo Data Management Web Services Q&A Feedback

Windows Mobile Devices Windows Mobile provides a variety of device types Pocket PC Smartphone Pocket PC Phone Edition

Windows Mobile Platform Common Win32 platform across device types Mobile versions of productivity tools Excel Mobile, Word Mobile, Pocket Outlook Simplified access to device extensions Camera, GPS, Phone

Thin Clients VS. Fat Client

Developing Mobile Applications NET Compact Framework 2.0 Leverage desktop .NET Framework skills Classes for forms, drawing, storage, net, data access, XML Optimized for smart devices (28% of coverage, 8% of size). Full support for VB.NET and C# language features Visual Studio 2005 Development experience consistent with desktop Automated application deployment Integrated device debugging Run managed .EXEs and .DLLs directly Debug with Visual Studio .NET Emulators Develop and debug applications without a device Emulator Manager provides centralized control

Windows Mobile Managed API’s Focus on simplifying device development Encapsulate common device tasks Global Positioning System interaction Camera and picture management 3-D Graphics and multimedia support State and Notifications Broker (SNAPI) Common repository for device information Phone state, battery life, what song is playing Sends notifications of changes in device state Network availability, arrival of phone call Arrival of SMS/email message

Data Management

Data Management SQL Server 2005 Mobile Edition (SQL Mobile) Full featured database running locally on device inner/outer joins, transactions, locking, much more Visual Studio 2005 support Server Explorer Create database, tables and indices Modify schema and data Database file can be located on device or desktop Forms Designer Controls created directly from table schema Data view and edit forms can be auto generated

SQL Mobile Synchronization Remote Data Access (RDA) Merge Replication SQL Mobile provides built-in server synchronization

Remote Data Access (RDA) Loosely-coupled Retrieve data from server and track local changes Send local changes back to server Very lightweight server cost requires URL pointing to DLL to allow data access. (i.e. http://192.168.1.100/sqlmobile/sqlcesa30.dll")

Merge Replication Tightly-coupled device and server schema Changes tracked on both device and server Device and server changes reconciled on synch Significant server cost DB File (.SDF) stored in a folder on the mobile device. (i.e. Data Source =" foldername + "RealEstate.sdf“)

SQL Server Everywhere •Essential relational database functionality in a compact footprint •Ideal for mobile and desktop applications, including occasionally connected •Embeddable in applications •Free to download, develop, deploy, and redistribute

SQL Server Everywhere Increase Productivity: SQL Server Everywhere allows developers and administrators to apply their existing SQL Server skills and be immediately productive. •Enables Deep Business Insight: SQL Server Everywhere, together with Business Intelligence in SQL Server 2005, allows you to extend your business insights further across the organization to distributed and mobile applications. •Reliability For Mission-Critical Business: Originally built on SQL Mobile technology, SQL Server Everywhere has self-healing and management technologies built designed to handle instant off and dead battery scenarios. •Better Value Over Time: As requirements and scale grow, SQL Server Everywhere can easily scale up to other editions of SQL Server.

Web Services & Mobile Apps Web services perfectly suited for mobile apps Can communicate with any enterprise platform Well suited for “casual” connectivity Inexpensive way to roll-out mobile solutions Provide internet access to enterprise resources Accessing web services same as on desktop Visual Studio Add Web Reference generates proxy Proxy class handles communications details

.Net Mobile Advantages Managed Code environment Garbage Collection Type safety Exception Handling Threading Organized .Net Classes ADO.Net Integration Platform Invoke (P/Invoke) service Integration with Web Services Single Vendor relationship Tight integration with Mobile API’s Remote Viewer Rich Graphics UI Faster application performance High Productivity with Visual Studio.Net Intellisense Remote debugging Common development experience Emulators provide accurate debug and development experience Separation of code, HTML, and scripts for easier debugging Multi-language support Reduced application development time Code Access Security Tight integration with other MS products Integration with SQL Server CE ActiveSync

Summary Windows Mobile Development Data Management Windows Mobile 5.0 Common development experience with desktop Emulators provide accurate debug and development experience Data Management SQL Mobile provides reliable local data store RDA and Merge Replication provide server synch Web services give easy access to server resources Windows Mobile 5.0 Simplifies common device tasks Standardizes system status and notification
