.NET Mobile Development .NET Mobile Web SDK .NET Mobile Development ASP.NET Mobile Controls Smart Device Programmability Thin client Remote Web Pages Smart client Local Code KEY MESSAGE: The .NET mobile device development model provides an effective solution for all needs, centralized around Visual Studio .NET SLIDE BUILDS: 4 SLIDE SCRIPT: Now that we have a fairly good idea of today’s development model, along with the common difficulties developers face, let’s take a look at how .NET provides a more effective model. BUILD The first key advantage of building mobile device applications using .NET lies in the IDE. Any developer who currently develops applications for the desktop or Web will be able to use the same tools and languages to target mobile devices, both server- and client-side. The Mobile Internet Toolkit extends Visual Studio .NET and the ASP.NET framework to scale to mobile devices. With a comprehensive understanding of devices of all shapes and sizes, the Mobile Internet Toolkit provides developers with an efficient way to build mobile Web applications that adaptively render to virtually all commercial mobile devices. Since all processing is on the server, MIT applications are able to take advantage of all of the same resources as ASP.NET desktop Web applications. In fact, the only difference between an ASP.NET desktop Web application and an MIT mobile Web application is the presentation layer. For client-side development, Microsoft provides the .NET Compact Framework, which is a layer of abstraction between code and the device operating system. By building software to target the .NET Compact Framework, developers don’t need to worry about the underlying operating system since their applications will work as expected on any device that supports the .NET Compact Framework. Building applications for the .NET Compact Framework is simplified with the Smart Device Extensions for Visual Studio .NET, which enable developers to use the same tools they already use for desktop development. The Smart Device Extensions package includes a desktop emulator, which runs a true Windows CE .NET operating system image in a virtual machine, providing exact emulation of the target device. SDE also provides remote debugging capabilities, enabling developers to debug applications while they run on actual production hardware.

SLIDE BUILDS: None SLIDE SCRIPT: Advantages of mobile Web applications include the following: Support for a very broad range of devices (more that 200 have been tested) Server-based Web browser access so no client software is needed Handling device capabilities Disadvantages include: Applications don't work offline Local processing power is not utilized for computation or heavy lifting of large data UI is limited Smart device application advantages include running both online and offline, taking full advantage of Pocket PC power, and having excellent integration with Microsoft® SQL Server™ Windows® CE. However, a smart device application runs only on Pocket PC and Windows CE .NET, and installation of the application onto the device is required.
