Had time to digest everything from BUILD yet? It sure is a lot to take in. We’ve blogged about some of the sessions: day 1, day 2 and day 3. A lot has been written about news and content from BUILD, here’s a distilled list of how the app landscape is improving with Windows 10. I hope this can provide some overview and guidance in the vast amount of info available. I have surely missed lots of great things, but this should at least get you started. Please note – these apps will run on all Windows 10 devices – ranging from IoT devices to Surface Hub and HoloLens.
- Bridges to Windows – create apps from existing code and publish to the Windows Store!
- Web – Package any web app, do feature detection to light up with native app features, eg live tiles and notifications.
- .NET/Win32 – Some limitations on the legacy code (eg no services), but all capabilites of Windows apps.
- iOS – Open your Objective-C code in Visual Studio and re-build as a Windows app. Voila!
- Android – SDK plugin for Eclipse etc that swaps Google services for Microsoft services, and reroutes all Java calls to the Windows kernel.
- One app – One Store
- Same binary runs on all Windows 10 devices – custom UI optional.
- Device family vs feature detection
- DeviceFamily needed in some cases (Universal, Desktop, Mobile, Team, IoT etc), but try to use feature detection (ApiInformation.IsTypePresent) as far as possible for normal apps.
- Converged API
- E.g. the PivotControl is now a Universal control, used to be Phone only. BackRequested is a Universal concept – Windows will have a back button in the task bar for tablet mode.
- Many new triggers (eg system managed SocketTrigger, BluetoothLE). ExtendedExecution upon suspend, until resources needed.
- App-to-app interaction
- Apps can launch other apps and ask for return data, apps can also create background tasks for other apps to call.
- Tiles & notifications
- Adaptive tiles and a tile template visualizer, super.
- XAML layout
- Visual State Triggers (including AdaptiveTrigger and custom) to create responsive UIs. Bindable events, useful for DataTemplates. New controls: RelativePanel, SplitView etc.
- XAML performance
- x:Bind – compiled bindings, much faster. x:DeferLoadStrategy – deferred loading of XAML block until visible. Lots of framework improvements, eg better XBF (XAML binary format).
- Almost the full performance of DirectX, from a few lines of C# – awesome. On 8.1 also.
- Designer now fully separated from XAML editor. Visual Tree Inspector for examining and editing XAML tree in runtime. Blend re-created with VS technology, now handles nuget, source code etc.
- One Store for all devices, admin roles for uploading/managing apps, translations, public/private responses etc. Business Store for enterprises.
