Windows 10: Official support for Windows 10 on ARM development

Brink · Nov 15, 2018

Today is an exciting day for Windows 10 on ARM. With the official release of Visual Studio 15.9, developers now have the officially supported SDK and tools for creating 64-bit ARM (ARM64) apps. In addition, the Microsoft Store is now officially accepting submissions for apps built for the ARM64 architecture.

This news comes at a great time, as this holiday season, our partners Lenovo and Samsung are offering new Windows 10 on ARM devices featuring the Qualcomm Snapdragon 850 processor. These second-generation ARM64 devices provide even more computing power for developers to tap into while continuing to deliver the beyond-all-day battery life customers expect from Windows 10 on ARM. Like the first-generation ARM64 devices, they are also thin, light, fast, and designed with instant-on 4G LTE connectivity in mind, while able to run the wide ecosystem of Windows applications thanks to an x86 emulation layer.

Developers can use Visual Studio 15.9 today to recompile apps – both UWP and C++ Win32 – to run natively on Windows 10 on ARM devices. Running natively allows applications to take full advantage of the processing power and capabilities of Windows 10 on ARM devices, resulting in the best possible experience for users.

Instructions

Back in May, we documented a number of steps needed in order to build as ARM64 using early preview tools. With official support in Visual Studio, that’s much easier.

To start, update to Visual Studio 15.9. If you are going to build ARM64 C++ Win32 apps, ensure you have installed the individual component “Visual C++ compilers and libraries for ARM64” as shown below:

After updating, for new UWP projects, you will see ARM64 as an available build configuration.

For existing projects, or for C++ Win32 projects, add an ARM64 configuration to your project:

Right click on your Solution and select Properties, then navigate to Configuration Properties and select “Configuration Manager.”

Under “Active solution platform:” select “<New…>” and call it ARM64. Copy settings from “ARM” or “x64” and check to create new project platforms.

Hit build, and you should have ARM64 binaries ready to run.

To debug your app, you can use remote debugging, which is fully supported on ARM64. The download and instructions can be found at Remote Debugging on docs.microsoft.com. You can also create a package for sideloading or directly copy binaries over to a Windows 10 on ARM device to run your app.

To deliver your app to customers, the Store is now accepting ARM64 UWP apps, both C++ and .NET Native. You can also use the Desktop Bridge (instructions on docs.microsoft.com) to wrap ARM64 binaries into a package that can be submitted to the Store. And as always, you can also host dedicated ARM64 versions of your Win32 apps on your website or integrate ARM64 into existing multi-architecture installers.

Conclusion

With new Windows 10 on ARM devices sporting more powerful processors, the ARM64 platform continues to mature and improve. The release of Visual Studio 15.9 continues that evolution, and we can’t wait to see what amazing experiences developers can produce using these tools.

Early preview Visual Studio support for Windows 10 on ARM development

Today, we are pleased to announce that Visual Studio 15.8 Preview 1 contains an early preview of the SDK and tools to allow you to create your own 64-bit ARM (ARM64) apps. These tools answer the requests of many eager developers, and the development made possible with these tools represents the next step in the evolution of the Always Connected PC running Windows 10 on ARM.

Earlier this year, our partners released the first Always Connected PCs powered by Qualcomm Snapdragon 835 processors. These Always Connected PCs are thin, light, fast, and designed with instant-on 4G LTE connectivity and unprecedented battery life – now measured in days and weeks, not hours. Thanks to an x86 emulation layer, these Always Connected PCs also allow customers to tap into the wide ecosystem and legacy of Windows apps.

Developers interested in targeting this new ARM-based platform can use these early preview tools to build apps that run natively on ARM processors rather than relying on the emulation layer. While the algorithms that make emulation possible are engineered to optimize performance, running your app natively allows your customers to get the most performance and capability from your app on this new category of devices.

Since this is an early preview, there isn’t official support yet for the ARM64 apps built with these tools. You won’t be able to submit ARM64 packages to the Microsoft Store, though you can post preview versions of ARM64 Win32 apps to your website. Stay tuned to this blog for more information as more support becomes available. In the meantime, you can use these preview tools to get a head start on developing your ARM64 apps and provide feedback before the tools are finalized.

In this post we’ll look at how to set up your environment to build ARM64 apps, whether you’re building Universal Windows Platform (UWP) apps or C++ Win32 apps.

C++ UWP App Instructions

To build ARM64 UWP apps based on C++, start by setting up your development environment:

1) Download Visual Studio’s latest preview at https://www.visualstudio.com/vs/
2) Choose the “Universal Windows Platform development” workload
3) Select the “C++ Universal Windows Platform tools” optional component
4) In Individual Components, select “C++ Universal Windows Platform tools for ARM64”

The Visual Studio Installer should look like this when everything that is required is selected:

After installing, you can get started on your app:

5) Open your C++ Project in Visual Studio, or create a new one
6) Right click on your Solution and select Properties, then navigate to Configuration Properties and select “Configuration Manager”
7) Under “Active solution platform:” select “<New…>” and call it ARM64. Copy settings from “ARM” and check to create new project platforms
8) If individual projects within the solution do not allow adding ARM64 as a platform, it may be because of dependencies. To learn more about the dependencies, you can modify those project files directly, copying the ARM configuration and modifying the platform to create an ARM64 configuration.
9) Save everything

ARM64 will now be available as a configuration for the project to build. Note that only Debug builds are supported for ARM64 at this time. You can create a package for sideloading or use remote debugging (see instructions) to run the app on a Windows 10 on ARM PC.

.NET Native UWP App Instructions

To build ARM64 UWP apps that rely on .NET Native, start by setting up your development environment.

1) Download Visual Studio’s latest preview at https://www.visualstudio.com/vs/preview/
2) Choose the “Universal Windows Platform development” workload
3) Open your project or create a new one. Note that the Target Platform Minimum Version must be set to at least “Windows 10 Fall Creators Update (Build 16299)”
4) Open the project file in your favorite editor and add a property group targeting ARM64. You can copy an existing property group, such as Debug|ARM, and modify it to support ARM64 with the changes highlighted below:

The UseDotNetNativeToolchain property is required to enable the .NET Native toolchain.

5) Save the project file and reload it in Visual Studio
6) Right click on your Solution and select Properties, then navigate to Configuration Properties and select “Configuration Manager”
7) Under “Active solution platform:” select “<New…>” and call it ARM64. Copy settings from “ARM” and check to create new project platforms
8) Update to latest ARM64 version of the tools:
a. Right-click your project and select ‘Manage NuGet Packages…’
b. Ensure “Include Prerelease” is selected
c. Select the Microsoft.NETCore.UniversalWindowsPlatform package
d. Update to the following version: 6.2.0-Preview1-26502-02

ARM64 will now be available as a configuration for the project to build. Note that only Debug builds of ARM64 are supported at this time. You can create a package for sideloading or use remote debugging (see instructions) to run the app on a Windows 10 on ARM PC.

C++ Win32 App Instructions

Visual Studio 15.8 Preview 1 also includes an early level of support for rebuilding your C++ Win32 apps as ARM64 to run on Windows 10 on ARM.

1) Download Visual Studio’s latest preview at Pre-release Visual Studio 2017 | Visual Studio Preview - Visual Studio
2) Choose the “Desktop development with C++” workload
3) In Individual Components, select “Visual C++ compilers and libraries for ARM64”
4) Open your project in Visual Studio or create a new one
5) Right click on your Solution and select Properties, then navigate to Configuration Properties and select “Configuration Manager”
6) Under “Active solution platform:” select “<New…>” and call it ARM64. Copy settings from “ARM” and check to create new project platforms.
7) Save everything
8) Open the project file in your favorite editor. Under <PropertyGroup Label=”Globals”>, declare support for ARM64 by adding WindowsSDKDesktopARM64Support, as highlighted below:

9) Save and reload the project

You will now be able to build the project as ARM64 and either remote debug on a Windows 10 on ARM PC or copy over the EXE files and run them directly.

You can also use the Desktop Bridge (see instructions) to wrap the built ARM64 binaries into a Windows app package that can be installed on Windows 10 on ARM PCs.

Conclusion

We’re excited to open up Windows 10 on ARM to developers looking to build great apps compiled natively for the platform.

Visual Studio 15.8 Preview 1 provides an early preview of the full support that will be coming later this year. You can expect more updates as we work to bring these tools to an official release and open the Store to accept submissions for ARM64 packages.

We hope you give these tools a try on your apps and would love to hear from you. If you hit any issues, have any questions, or have feedback to share, head to our Windows 10 on ARM development page at Windows 10 on ARM or leave comments below.

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.
