Package your add-in using Visual Studio to prepare for publishing

Your Office Add-in package contains an XML file that you'll use to publish the add-in. You'll have to publish the web application files of your project separately.

Deploy your web project and package your add-in by using Visual Studio 2015

To deploy your web project

  1. In Solution Explorer, open the shortcut menu for the add-in project, and then choose Publish.

    The Publish your add-in page appears.

  2. In the Current profile drop-down list, select a profile or choose New ... to create a new profile.

    Note A publish profile specifies the server you are deploying to, the credentials needed to log on to the server, the databases to deploy, and other deployment options.

    If you choose New ..., the Create publishing profile wizard appears. You can use this wizard to import a publishing profile from a web site hosting provider such as Microsoft Azure or create a new profile and add your server, credentials, and other settings in the next procedure.

    For more information about importing publishing profiles or creating new publishing profiles, see Creating a Publish Profile.

  3. In the Publish your add-in page, choose the Deploy your web project link.

    The Publish Web dialog box appears. For more information about using this wizard, see How to: Deploy a Web Project using On-Click Publishing in Visual Studio.

To package your add-in

  1. In the Publish your add-in page, choose the Package the add-in link.

    The Publish Office and SharePoint Add-ins wizard appears.

  2. In the Where is your website hosted? dropdown list, select or enter the URL of the website that will host the content files of your add-in, and then choose Finish.

    You have to specify an address that begins with the HTTPS prefix to complete this wizard. In general, using an HTTPS endpoint for your website is the best approach, but it is not required if you don't plan to publish your add-in to the Office Store. After the package is created, you can open the manifest in Notepad and replace the HTTPS prefix of your website with an HTTP prefix. For more information, see Why do my add-ins have to be SSL-secured?.

    Note Azure websites automatically provide an HTTPS endpoint.

    Visual Studio generates the files that you need to publish your add-in and then opens the publish output folder.

If you plan to submit your add-in to the Office Store, you can choose the Perform a validation check link to identify issues that will prevent your add-in from being accepted. You should address all issues before you submit your add-in to the store.

You can now upload your XML manifest to the appropriate location to publish your add-in. You can find the XML manifest in OfficeAppManifests in the app.publish folder. For example:

%UserProfile%\Documents\Visual Studio 2015\Projects\MyApp\bin\Debug\app.publish\OfficeAppManifests
