[RESOLVED] Publishing A Mandatory Update With ClickOnce

I'm trying to add an automatic update feature if there is a mandatory update for my application using something like this:

vb.net Code:

'Check for mandatory updates
    Private Sub MyApplication_CheckForUpdateCompleted(ByVal sender As Object, ByVal e As Deployment.Application.CheckForUpdateCompletedEventArgs)
        If e.UpdateAvailable AndAlso e.IsUpdateRequired Then
            AddHandler My.Application.Deployment.UpdateCompleted, AddressOf Me.MyApplication_UpdateCompleted
            My.Application.Deployment.UpdateAsync()
        End If
    End Sub
 
    Private Sub MyApplication_UpdateCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs)
        If e.Error Is Nothing Then
            MessageBox.Show("The application has installed a mandatory update and needs to be restarted.", "Update installed", MessageBoxButtons.OK, MessageBoxIcon.Information)
            RemoveHandler My.Application.Deployment.UpdateCompleted, AddressOf Me.MyApplication_UpdateCompleted
            Application.Restart()
        End If
    End Sub

My question is: how do I publish a mandatory version? I see no way of specifying when you publish that it is a required update.

On the Publish tab of the Project Properties dialog click on the Updates button and specify the minimum required version, make sure the Publish Version is the same.

I figured it would be something easy, thanks!
