WPF FAQ - ClickOnce

Yes. ClickOnce allows you to add prerequisites in ClickOnce deployment. It should download the installer packages for those prerequisites to your development machine. When you publish the ClickOnce application, choose Download prerequisites from the same location as my application. An error will occur if the installer packages aren’t in the Packages folder.

ClickOnce allows the vendors to provide regular updates for the applications. To enable automatic updates, select ‘publish’ tab in Project Properties window and click on the ‘updates’ button. In the Application Updates window, select the mode of application updates like ’after application starts’ and ’before application starts’. The former mode is used when there is a need to provide regular updates of the application after a period of time and in the later mode, the application checks for the updates only once, that is when the application runs for the first time. Click OK to close the Application Updates window and publish the application.

ClickOnce allows you to deploy windows based applications to a client system using the web or file server. The application files are placed on the web or FTP site or local share and the user is provided with a link in case of web and FTP deployment. On clicking the link, the application files get downloaded and installed. When a new version or update is available, it can be automatically detected and applied to the clients using the optional deployment settings. In case of a local share deployment, the application can be installed similar to other windows based applications.
