  • you should do this outside clickonce functions, for example the client should check with server latest version in a ThreaPool thread often and when new version is available popup a warning in main UI thread instructing user to close and open the app for an update.

  • You can use the ClickOnce update API to do the update programmatically.


    Then you can show user a alert to see there's new version after you check there's really a new version could install.

    if (info.UpdateAvailable)
          Boolean doUpdate = true;
          if (!info.IsUpdateRequired)
            DialogResult dr = MessageBox.Show("An update is available. Would you like to update the application now?", "Update Available", MessageBoxButtons.OKCancel);

    Best wishes,

  • Why not use the auto-update feature? It will automatically check for updates and install them before running the application. You can decide whether the updates need to be required or not.

    This is set in the Updates dialog in the Publish tab of your project's properties.
