You can deploy apps on four different paths: Mobile Device Management (MDM), Microsoft Store, Provisioning, or by installing them via App Installer.
Mobile Device Management (MDM)
An MDM solution enables IT decision-makers and administrators to privately auto install (push) their in-house, line-of-business apps, or purchase apps through the store for a group of users. HoloLens devices work best with Microsoft Intune for application management. Intune also offers users finer-grained control over IT-managed apps through the Company Portal downloadable experience.
Note
The following instructions are for users who want to manage their applications with Intune. Microsoft recommends using Intune for application and device management.
Mobile Device Management (MDM) is applicable for:
MDM deployed + Company Portal
Line of Business (non public) apps
Manual installation of available applications through Company Portal
Admin push through MDM policy
Auto update through MDM
Microsoft Store
The Microsoft Store provides IT decision-makers and administrators in businesses to find, acquire, manage, and distribute public apps.
Provisioning Packages allow you to install custom or Line of Business apps, allowing IT pros and administrators to install apps quickly to a local device(s) via USB. This installation can be done without an internet connection and for any identity type.
Installing via Provisioning Packages is applicable for:
Line of Business / Self-developed (non public) apps
Public apps (if offline installer is available)
USB side-loading only
No auto update (requires manual updates via Provisioning Package)
Install Apps on HoloLens 2 via App Installer
With the App Installer, users can have an experience that is simple for either installing Apps on local devices or sharing an app with someone else who is unfamiliar with other app install methods on HoloLens. This method does not need to enable Developer Mode or use Device Portal. It is a simple method of distributing a built app. It also works easily, whether you'd like to deploy your app or you simply want to demo your app to another user with a HoloLens.
Installing via App Installer is applicable for:
Line of Business / Self-developed (non public) apps
Plan and execute an endpoint deployment strategy, using essential elements of modern management, co-management approaches, and Microsoft Intune integration.
