Install the tools
Get the tools you need to build applications for Microsoft HoloLens and Windows Mixed Reality immersive (VR) headsets. There is no separate SDK for Windows Mixed Reality development; you'll use Visual Studio with the Windows 10 SDK.
Don't have a mixed reality device? You can install the HoloLens emulator to test some functionality of mixed reality apps without a HoloLens. You can also use the Windows Mixed Reality simulator to test your mixed reality apps for immersive headsets. If you're using Unity, you can use Mixed Reality Toolkit (MRTK)'s input simulation to test various types of input interactions such as hand-tracking and eye-tracking input.
We recommend installing the Unity game engine as the easiest way to get started creating mixed reality apps. However, you can also build against DirectX if you'd like to use a custom engine.
Bookmark this page and check it regularly to keep up-to-date on the most recent version of each tool recommended for mixed reality development.
Windows 10 (Manual install link)
Install the most recent version of Windows 10 so your PC's operating system matches the platform for which you're building mixed reality applications.
|Installing Windows 10
You can install the most recent version of Windows 10 via Windows Update in Settings or by creating installation media, using the link in the left column.
See current release notes for information about the newest mixed reality features available with each release of Windows 10. Enable developer mode on your PC at Settings > Update & Security > For developers.
Note for enterprise and corporate-managed PCs
If your PC is managed by an your organization's IT department, you might need to contact them in order to update.
'N' versions of Windows
Windows Mixed Reality immersive (VR) headsets are not supported on 'N' versions of Windows.
Visual Studio 2019 (16.2 or higher) (Install link)
Fully-featured integrated development environment (IDE) for Windows and more. You'll use Visual Studio to write code, debug, test, and deploy.
|Be sure you install the following workloads:
● Desktop development with C++
● Universal Windows Platform (UWP) development
Within the UWP workload, be sure to check the following optional component if you'll be developing for HoloLens:
● USB Device Connectivity
Note about Unity
Unless you're intentionally trying to install a newer (non-LTS) version of Unity for a specific purpose, we recommend not installing the Unity workload as part of Visual Studio installation, and instead install the Unity 2019 LTS stream as noted below.
There are some known issues with debugging mixed reality apps in Visual Studio 2019 version 16.0. Please ensure that you update to Visual Studio 2019 version 16.2 or higher.
Windows 10 SDK (10.0.18362.0) (Manual install link)
Provides the latest headers, libraries, metadata, and tools for building Windows 10 apps on HoloLens 2.
|To build HoloLens 2 apps, you must install the Windows SDK, build 18362 or later.
If you are only developing applications for desktop Windows Mixed Reality headsets or HoloLens (1st gen), you can use the Windows SDK installed by Visual Studio 2017.
HoloLens 2 Emulator (Windows Holographic, version 2004 June 2020 Update) (Install link: 10.0.19041.1106)
HoloLens (1st gen) Emulator (Install link: 10.0.17763.134)
The emulator lets you run applications on a HoloLens virtual machine image without a physical HoloLens.
|See Using the HoloLens emulator for more information on getting started with the emulator.
Your system must support Hyper-V for the emulator installation to succeed. Reference the System Requirements section below for details.
Choose your engine
Now that you have your Windows 10, Visual Studio, and Windows 10 SDK ready to go, let's choose an engine to build on.
1. Download the latest version
We recommend the Unity LTS (Long Term Support) stream as the best version to use when starting new projects, updating to its latest revision to pick up the latest stable fixes.
- The current recommendation is to use Unity 2019, which is the LTS build required for MRTK v2 below.
- If you need to use a different version of Unity for specific reasons, Unity supports side-by-side installs of different versions.
2. Import Mixed Reality Toolkit (MRTK)
Mixed Reality Toolkit (MRTK) is an open-source, cross-platform development kit for mixed reality applications. MRTK provides a cross-platform input system, foundational components, and common building blocks for spatial interactions. The toolkit is intended to accelerate the development of applications targeting Microsoft HoloLens, Windows Mixed Reality immersive (VR) headsets, and the OpenVR platform.
If you don't want to use MRTK for Unity, you'll need to script all interactions and behaviors yourself.
Other tools [optional]
- Mixed Reality Companion Kit (GitHub) - code bits and components that might not run directly on HoloLens or immersive (VR) headsets, but instead pair with them to build experiences targeting Windows Mixed Reality.
- Mixed Reality Toolkit - Common (GitHub) - a collection of shared scripts and components.
3. Set up your PC for Mixed Reality development
The Windows 10 SDK works best on the Windows 10 operating system. This SDK is also supported on Windows 8.1, Windows 8, Windows 7, Windows Server 2012, Windows Server 2008 R2. Note that not all tools are supported on older operating systems.
You can develop and deploy your apps for HoloLens, VR immersive headsets, or both. Make sure you fulfill the requirements below depending on your needs.
For HoloLens development
When setting up your development PC for HoloLens development, please make sure it meets the system requirements for both Unity and Visual Studio. If you plan on using the HoloLens emulator, you'll want to make sure your PC meets the HoloLens emulator system requirements as well.
To get started with the HoloLens emulator, see Using the HoloLens emulator.
If you plan to develop for both HoloLens and Windows Mixed Reality immersive (VR) headsets, use the system recommendations and requirements in the section below.
Immersive (VR) headset requirements
The following guidelines are the current minimum and recommended specs for your immersive (VR) headset development PC, and are updated regularly.
Do not confuse this with the minimum PC hardware compatibility guidelines, which outlines the consumer PC specs to which you should target your immersive (VR) headset app or game.
If your immersive headset development PC does not have full-sized HDMI and/or USB 3.0 ports, you'll need adapters to connect your headset.
There are currently known issues with some hardware configurations, particularly notebooks that have hybrid graphics.
