私はWebサーバにアップデートを公開しており、プログラムでダウンロードしてインストールすることはありません。 次のコードを置いても動作しません。vb.net Applicationdeployment.isnetworkdeployed falseを返す

(ApplicationDeployment.IsNetworkDeployed)場合、

条件リターン偽ノーコードが実行された場合。

Imports System.Deployment.Application 
Public Class Form1 
    Private Sub InstallUpdateSyncWithInfo() 
     Dim info As UpdateCheckInfo = Nothing 
     System.Diagnostics.Debugger.Launch() 
     If (ApplicationDeployment.IsNetworkDeployed) Then 
      Dim AD As ApplicationDeployment = ApplicationDeployment.CurrentDeployment 
      MsgBox("inside if ") 
      Try 
       info = AD.CheckForDetailedUpdate() 
      Catch dde As DeploymentDownloadException 
       MessageBox.Show("The new version of the application cannot be downloaded at this time. " + ControlChars.Lf & ControlChars.Lf & "Please check your network connection, or try again later. Error: " + dde.Message) 
       Return 
      Catch ioe As InvalidOperationException 
       MessageBox.Show("This application cannot be updated. It is likely not a ClickOnce application. Error: " & ioe.Message) 
       Return 
      End Try 

      If (info.UpdateAvailable) Then 
       Dim doUpdate As Boolean = True 

       If (Not info.IsUpdateRequired) Then 
        Dim dr As DialogResult = MessageBox.Show("An update is available. Would you like to update the application now?", "Update Available", MessageBoxButtons.OKCancel) 
        If (Not System.Windows.Forms.DialogResult.OK = dr) Then 
         doUpdate = False 
        End If 
       Else 
        ' Display a message that the app MUST reboot. Display the minimum required version.

         "version to version " & info.MinimumRequiredVersion.ToString() & _
