Specify a link for Technical Support
When publishing a ClickOnce application, the Support URL property identifies a Web page or file share where users can go to get information about the application. This property is optional; if provided, the URL will be displayed in the application's entry Add or Remove Programs dialog box.
The Support URL property can be set on the Publish page of the Project Designer.
To specify a support URL
With a project selected in Solution Explorer, on the Project menu, click Properties.
Click the Publish tab.
Note
In ClickOnce for .NET Core 3.1 and .NET 5 or later, you set deployment properties using the Publish tool instead of the Publish wizard and the Publish page of the Project Designer. For more information, see Deploy a .NET Windows application using ClickOnce and ClickOnce for .NET.
Click the Options button to open the Publish Options dialog box.
Click Description.
In the Support URL field, enter a fully qualified path to a Web site, Web page, or UNC share.
