Editor's Notes
- Looking to improve the development ecosystem at every level Already know about improvements to the Core OS. Relased all the time. Features and tools – ongoing improvement, and large point releases. Hey, what did I say about BUILD? Really it’s all about what we’re doing to make the third level – above OS and tools, but below the devices, attractive to developers and vendors alike: focus on growing middleware partnerships; ensuring they’re tightly woven into our tooling; work closely with hardware vendors & makers to create opportunities at every level; and finally, create awareness. Used events, but really it’s shorthand for using both owned and external channels to showcase both internal and external events. New commitment to taking the gaming show on the road for more dev-centric opportunities; creation of dev-centric evidence pieces that we promote.
- Strong initial acceptance of Windows 10 has really taken over PC gaming: last survey from February, combined Win10 numbers are likely over 40% right now Xbox One as a Windows 10 device bringing UWP content to console gaming in 2016 – soon IoT Core – Raspberry Pi 3 running Windows 10 Surface Pro 4 and Surface Book. Gamers are *really* into them – dedicated GPUs for Surface Book, and SP4 offers many core gaming scenarios not possible elsewhere But what do those big numbers actually mean?
- The unified Windows core and app model powering the game experiences across these Windows devices is the Universal Windows Platform or UWP. UWP provides common APIs that can be used across all different devices powered by Windows 10. Alongside these common APIs, there are extensions available for each of the platforms that offer distinct capabilities (such as Mobile, Xbox and Desktop). These extension APIs work with our API contracts functionality to enable developers to light up features on devices that have these capabilities, but ensure the core of the app works across all devices. UWP also provides a number of UI frameworks, such as Windows XAML, DirectX and HTML to act as the user interface layer of the apps. Next to APIs, UWP also provides an app model that looks after the complete lifecycle of the games, from installation to uninstallation, providing a cleaner way for games to be installed, run, updated and uninstalled, preventing “Windows rot”. The app lifecycle also provides limited background execution of apps (only one foreground app executes at a time, with mechanisms in the OS to ask for specific background task execution (on a schedule, triggered by various events (e.g. Internet/Bluetooth connectivity, power changes, etc.) and in specific scenarios such as music playing or GPS tracking). The third part of UWP is the unification of the services, providing a single distribution and monetization mechanism through the Windows Store. The notification model has also been unified, enabling developers to send notifications in a single format to the various Windows devices. A light-weight model to roam data across devices is also provided to reduce complexity in providing settings and small amounts of data across devices. <click> Finally, we haven’t forgotten about existing developers who have invested in building desktop applications and experiences on the web. We’ll talk about these “bridges” later in this presentation and how you can re-use your existing code to accelerate bringing your game experiences to the Universal Windows Platform.

- I am sure some of you are thinking: One API, across a myriad of devices with very different hardware characteristics.. It is not doable… You are right-on… How Direct3D takes care of this is through Feature levels…
- Collaborating w/ DirectX team on HDR / Wide Color Gamut Support which is part of the REC 2020 standard. HDR is a key differentiator, ideally targeted at game scenarios, and has broad adoption across all the major TV and PC monitor manufacturers announced at CES 2016 Leveraging the expanded color space adds an additional level of clarity and image fidelity with minimal engineering and content changes HDR support will be available as a preview later this year on Windows 10 === If a game uses phisically based rendering, high dynamic range support can be added with a “very minimal engineering cost.” That’s because PBR already generates most of the data necessary for HDR. ==== We keep saying this is coming this year. How will it be rolled out? Is it in RS1? Does it have a different shipping vehicle? [For Arthur] [AY] Xbox: preview available in March 2016 XDK. The RS1 mid-year release will officially add HDR support. PC: RS1 supports a developer preview that allows developers to output HDR. RS2 preview is required for a full set of APIs. RS2 is also required for consumers to get HDR as a feature. I assume API is available to both Xbox and UWP app models, right? [For Arthur] [AY] Yes – with the timelines in question 1). What are the hardware requirements for HDR? Do I need a specific graphics card? Is it a specific DX feature level? [Claude] Arthur, correct me if I’m wrong, but as far as I know you don’t need a specific graphics card, as long as the graphics driver can send the data over HDMI correctly to the TV, it should work. I.e. it doesn’t matter what graphics card or which DX feature level you use, just have to send the data in the correct format over HDMI. You’ll need a HDR capable TV though, which could mean many things. [AY] On PC, the driver will need to support WDDM 2.1, which essentially means at least a DX12 card. It is my understanding we are doing Rec 2020.. but not sure how that maps to Rec 709... is the latter the superset? Would we support 709 too? Or did we ‘skip it’.. [Claude] We’re supporting HDR10, which means Rec.2020 color primaries + ST.2084 transfer function. For SDR we have Rec.709 color primaries + Re.c709 gamma curve. Rec.2020 allows to represent a lot more colors than Rec.709, and ST.2084 allows to perceive actual bright values, vs. currently only perceiving up to white. For Windows, DWM will take care of legacy and new HDR content automatically. [AY] What Claude said - Rec 2020’s color space is larger than Rec 709’s.

- Main areas of middleware use in apps include products that help with development, analysis, user acquisition, and monetization. Middleware that helps develop apps takes advantage of solutions that allow a common code base to be used across platforms as well as tools to help with A/B testing, crash reporting, etc. Leading providers such as Unity, Cocos2d-x, Marmalade, Wave Engine, HockeyApp, Crittercism, BugSense support apps built on UWP Analysis of usage and behavior with apps enables developers to optimize for usability, customer satisfaction and monetization. Visual Studio Application Insights and Mobile Engagement, Adobe Analytics, and Localytics provide solutions for UWP apps User acquisition puts the ability to promote and gain users in the hands of the developers. Many different strategies can be employed such as improving attribution, retargeting, or programmatic marketing. Facebook, Vungle, Kochava, Urban Airship offer services to drive user acquisition Monetization of apps is a key aspect of a viable ecosystem. Monetization can be through direct payment using the Microsoft Store commerce capabilities for charging per download or for in app purchases. Additionally, advertising offers monetization opportunities and Microsoft Ads, Smaato, Inneractive, Pubmatic, and AdDuplex offer solutions for Windows apps.
- That’s why we’re so passionate building Universal Windows Platform Bridges that let you start with your code, no matter where it was born and bring it to the Universal Windows Platform and Store .
- Three chunks Clang/LLVM, c1/c2, CTP of arm32, build for phone Mentioned APIs, dozens more, not just that, import directly to Visual Studio, laid out in XIBs not programmatically, still preserved Not just syntax highlighting, mix and match XAML, not just UI, full access to UWP APIs Bridge is a bolt-on SDK, so you can use as much or as little as you want to, think about it, access to so much
- Previously announced as Project ‘Centennial’ and now an integral part of Windows 10 and the Universal Windows Platform is Microsoft’s bridge for existing desktop apps, like Win32 and .NET With the Desktop App Converter, package your existing desktop apps the same way as a UWP app, giving the you and the user the benefit of the streamlined (un)installation process while still delivering the full use of your existing app your users are familiar with. This is essentially a different installer technology which abstracts the app’s initial file system and registry operations so that installation and removal is an entirely discrete process and the app cannot make persistent changes to these systems during installation Additionally, the app is given an app identity after the conversion process, which is the key to accessing many of the newer UWP APIs, allowing your existing desktop application to make use of all of the new differentiated features such as Live Tiles, notifications, Cortana, and more This opens up the opportunity to either enhance your app with UWP APIs directly from your existing code or adding a UWP process to the app package, which can be used to migrate the app, add XAML UI, app services and more. Note that existing desktop apps converted this way can only run on systems on which they ran before (that is, they remain bound to desktop) until they are migrated to stop using the desktop extensions
