Confusion about possibility of publishing a VSTO Add-In to Windows Store or Office Store RRS feed

  • Question

  • We've read conflicting messages about whether or not a VSTO Add-In can be published to a Windows App Store or an Office App Store. First,

    VSTO Add-in:

    1. It's an application also know as Office Solution. From this MSDN article: You can use the Microsoft Office developer tools in Visual Studio to create .NET Framework applications that extend Office. These applications are also named Office solutions
    2. Also see Programming VSTO Add-in.
    3.  Deploying an Office Solution (i.e, VSTO-AddIn). You can use either ClickOnce technology or Windows Installer

    Office-Add-in:

    Use web based technology. These Add-ins enable you to extend Office clients such as Word, Excel, PowerPoint, and Outlook using web technologies like HTML, CSS and JavaScript. [Ref: Office Add-ins]

    Question: Can someone please clarify the following confusion? In our Stack Overflow post here about our VSTO Add-in, some users seem to indicate that we can upload my VSTO Add-in to Office App Store and not to Windows App Store. But according to a Microsoft Employee Michael Zlatkovsky in his response to a similar question on an MSDN forum here: VSTO add-ins should be able to be listed in the Windows Store as desktop app.

  • The WORD Add-in is developed using VSTO in Visual Studio 2015. It has a custom ribbon with some buttons that perform certain content manipulation of a WORD Document. Can this be converted to a UWP app using, maybe, Desktop App Converter , Desktop Bridge etc. And then be published to Windows 10 App Store.  Note: It does not have to run on all devices - it's ok if it runs only on a Windows 10 desktop as a WORD Add-In.

  • Hello,

    Currently, we can upload Windows Phone app and UWP app to the Store. We surely can use Desktop App Converter to publish the desktop app. However, the converter does not support VSTO product for the time being.

    You can choose to submit a feature request through the Windows 10 Feedback hub. Besides, Office Store currently doesn't support official publish for your VSTO add-in.

    Best regards,

  • Hello,

    >In our Stack Overflow post  here about our VSTO Add-in, some users seem to indicate that we can upload my VSTO Add-in to Office App Store and not to Windows App Store.

    Firstly, Office Store only accept web based office add-in so you're not able to upload your VSTO developed add-in to Office Store for official publishing.

    You might refer to Office Add-ins platform overview.

    >But according to a Microsoft Employee Michael Zlatkovsky in his response to a similar question on an MSDN forum  here: VSTO add-ins should be able to be listed in the Windows Store as desktop app.

    Please note that the response from @Michael Alatkovsky was from 2013, which was indeed correct at that time. Also, you could refer to the third article provided by him: the content removed, desktop application has been not a part of our new Windows 10 Store. The existing desktop app can still be available to Windows 8.x users but cannot be updated in Dev Center.

    However, the desktop app converter currently can only enable you to bring your existing desktop apps written for .NET 4.6.1 or Win32 to UWP, VSTO developed app is not supported.

    You might submit a feature request through Windows 10 Feedback Hub or contact Dev Center support to discuss if there exists any other option for you.
