WCF - 在服务器上进行线程化以更快地释放到客户端

Question

当函数调用服务器时，文件将上载并存储在文件夹中。然后必须处理该文件，这需要一些时间，并会导致客户端超时。

为了解决这个问题，我想通过将文件的处理放在一个单独的线程中，以允许子程序在文件上传后返回到客户端。并且文件的处理将在后台继续。

不幸的是，线程正在停止返回。我不明白我遇到了什么问题。我认为通过使用线程，它将允许子例程完成并返回到客户端。

Public Sub RestoreToOps(rFileInfo As RemoteFileInfo) Implements IRestore.RestoreToOps
    Dim oLogItem As New LogItem
    Dim sDestinationFolder As String = My.Settings.DestinationFolder
    Try
        Dim sFileDestination As String = Path.Combine(sDestinationFolder, rFileInfo.FileName)
        If File.Exists(sFileDestination) Then
            File.Delete(sFileDestination)
        End If
        Using fs As FileStream = New FileStream(sFileDestination, FileMode.Create, FileAccess.Write, FileShare.Read)
            fs.Write(rFileInfo.FileBytes, 0, rFileInfo.FileBytes.Length)
        End Using
        ProcessFile(rFileInfo.FileName)
    Catch ex As Exception
        'Error Handling
    End Try
End Sub

'*************************************************************************

Private Function ProcessFile(ByVal FileName As String) As Boolean
    Dim oThread As Thread = Nothing
    Dim oObject As Object = Nothing
    Dim oLogItem As New LogItem
    Dim sDBName As String = ""
    Dim bSuccess As Boolean = False
    Try
        If InStr(FileName, "Move.zip") > 0 Then
            sDBName = Replace(FileName, "Move.zip", "")
            oThread = New Thread(New ParameterizedThreadStart(AddressOf MakeRestoreFromObject))
            oThread.IsBackground = True
            oThread.Start(sDBName)
            oThread.Join()
        End If
    Catch ex As Exception
        'Error Handling
    End Try
    Return bSuccess
End Function

函数“MakeRestoreFromObject”需要相当长的时间，当使用上面的编码时，子程序在返回之前等待函数完成.....
