Distribute your MSIX in a consumer environment
If you are not an enterprise developer, retail distribution of MSIX can be done through normal retail channels. This includes hosting the MSIX on a web page.
Microsoft Store
The Microsoft Store can be an excellent way to distribute your application. It has been available to consumers since the launch of Windows 8 in late 2012. Users can browse, search and download apps or games for Windows.
For details on the Microsoft Store and its capabilities, see Microsoft Store.
To get started on publishing an app to the Microsoft Store and its capabilities, see the Partner Center
App Center
App Center enables you to automatically build your app, test it on real devices, and distribute it to beta testers. App Center lets you ship apps more frequently, at higher-quality, and with greater confidence. With App Center you can connect your repo and within minutes automate your builds, test on real devices in the cloud, distribute apps to beta testers, and monitor real-world usage with crash and analytics data. All in one place. For more information on App Center see App Center.
Web Install
While a MSIX file can be hosted on any IIS server. You can dramatically improve the experience by enabling direct install with App Installer. Direct install will allow the AppInstaller to launch immediately and run the install from the web server rather than downloading it first. For more details on Web install, see Installing Windows 10 apps from a web page.
