11. Edge WebView control
for Office Add-ins
Sudheer Maremanda, Sr. Program Manager

12. We heard
your feedback

14. Edge WebView
for Office Add-ins platform
Modern Edge WebView powers the runtime for
Office Add-ins

15. Context
Office Add-ins are built using HTML / JS and the platform uses the web
control available on the OS as the runtime for the add-in.
See here for more information on browser versions supported and platform
requirements for running Office add-ins
Platform Web control used
Win32 IE / Trident
Mac WebKit 2
iOS WebKit 2
Android Chromium
Online Browser [Edge, Chrome, Firefox, Safari]

16. Edge
WebView
Edge WebView control is the modern web control
available on Windows 10
- Performance, standards compliant
- Supports full set of HTML 5 features including
media, recording, location
- Support for ECMAScript 2015+
Starting with Windows 10 version 19XX
and Office 16.0.11326.20000, Edge
WebView control will be rolled out as the
default control on Win32 for Office add-
ins.

17. Impact of this rollout
• Starting with Office version 16.0.11326.20000, Edge control will be the default
control where available
• On Windows 18XX and lower builds we will continue to use IE / Trident as the
default web control
• This means – you may have to make a few changes to make your add-in work on
both the IE/Trident as well as the Edge WebView control
• This change does not impact:
• Versions of Office lower than 16.0.11326.20000. We will continue to use IE /
Trident as the web control there
• Non-Windows Office versions, such as Office on Mac, iOS, Android, and Office
Online

18. Call to Action
• Test your add-in[s] with the new Edge control and give us feedback
• Make any changes necessary to your add-in to support both IE/Trident and
Edge WebView
• Report issues on GitHub under OfficeDev/Office-js
• It’s your responsibility to make changes [that may be needed] to your add-in to support Edge
WebView
• Only report issues that you cannot address using standard web development practices [Eg:
Crashes, Scroll issues etc]
To test your add-in
• Get the latest preview versions of Office and Windows
• Min Office version 16.0.11326.20000
• Min Windows version 19XX
• Enable the following feature flight in Office
• Microsoft.Office.OEP.Win32WebView = true
• Restart the Office app
• Note: For debugging use Edge Dev Tools [see details]

19. Timeline
Now
Available in Insider / Preview builds
• Office, version 16.0.11326.20000
• Windows version 19XX
End of Feb
Rollout of Edge control with Office’s Feb fork behind a
feature flight
End of March
General Availability of this feature with March fork
[which should be publicly available in mid April]
You must be a member of Office Insiders and Windows Insiders to get access to these builds.

20. Known Issues
[current]
- Error occurred while trying to reach your add-in from
https://localhost
• When loading an Office add-in from https://localhost or when using Fiddler, you
may see an error stating that a problem occurred while trying to reach your add-
in.
• To fix this, follow either of these steps to add a local loopback exemption to
“Desktop App Web Viewer”:
• Open a command prompt as Administrator and run the following
command: CheckNetIsolation LoopbackExempt -a -
n="microsoft.win32webviewhost_cw5n1h2txyewy"
• Using Fiddler: Select Tools > Win8 Loopback Exemptions and add an
exemption to “Desktop App Web Viewer.”
- All certificates need to be in computer store.
- https://github.com/OfficeDev/generator-office/blob/master/src/docs/ssl.md
- Navigating to sub-domains of source location is broken
- Add list of all subdomains to AppDomains in manifest
