Asynchronous submit with events via COM interface

[SAS-Fan]

I am asynchronously submitting SAS code via the COM interface. Since it seems to be documented best, let's use Visual Basic to achieve this:

Programming with Visual Basic 

This documentation is somewhat rudimentary. So if you know a more detailed resource, I'd appreciate it very much to be told about it.

Anyway, here is my attempt to asynchronously submit SAS code from Visual Basic:

Option Explicit On

Imports SAS
Imports SASObjectManager

Module Program

    Private WithEvents ls As LanguageService
    Private Sub ls_SubmitComplete(ByVal Sasrc As Long)
        System.Console.WriteLine("Completed." + Sasrc)
    End Sub

    Sub Main(args As String())
        Dim factory As New ObjectFactory()
        Dim server As New ServerDef()

        server.Protocol = 2
        server.MachineDNSName = "*** HOSTNAME ***"
        server.Port = 8591

        Dim workspace As Workspace = factory.CreateObjectByServer("Workspace", True, server, "** USER ***", "*** PASSWORD ***")

        ls = workspace.LanguageService
        ls.Async = True
        ls.Submit("%put Test;")

        System.Threading.Thread.Sleep(10000)
    End Sub

End Module

Here, I tried to adapt the approach described in Receiving events and the more detailed but outdated LanguageService Object.

The problem is that, even though the submit completes successfully, ls_SubmitComplete is never called, i.e. the message "Completed." won't appear.

Could anyone help me how to properly receive and handle such events?

I think it would be safe to assume that you are using a little-used way to interface with SAS given the lack of response on the Community. You could try a Tech Support track or if you explained your business need in more detail perhaps there is a better-supported approach.
