When publishing a ClickOnce application for the first time, publish properties can be set using the Publish Wizard. Only a few of the properties are available in the wizard; all other properties are set to their default values.
Subsequent changes to publish properties are made on the Publish page in the Project Designer.
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.
Publish Wizard
You can use the Publish Wizard to set the basic settings for publishing your application. This includes the following publishing properties:
Publishing Folder Location - where Visual Studio will copy the files (local computer, network file share, FTP server, or Web site)
Installation Folder Location - where end users will install from (network file share, FTP server, Web site, CD/DVD)
Online or Offline availability - if end users can access the application with or without a network connection
Update frequency - how often the application checks for new updates.
Describes how to set the ClickOnce Publish Version property, which determines whether or not the application that you are publishing will be treated as an update.
This dialog box allows you to specify how the files in your project are categorized for publishing, dynamic downloading, and updating. It contains a grid that lists the project files that are not excluded by default, or that have a download group.
