[Freeswitch-users] Re-2: Help with mod_managed under Windows

Hi Michael,

I found the problem. I had a version mismatch between mod_mamanged and my FS installation. So this is solved, but now I am running into the next problem. I have written a small Class that is nearly similar to the one on the wiki pages. The source is here (VB.NET)

Imports FreeSWITCH
Public Class AppDemo
    Inherits AppFunction
    Public Shadows Function Load()
        Log.WriteLine(LogLevel.Info, "Inside AppDemo Load.")
        Return True
    End Function
    Protected Overrides Sub Run()
        Session.Answer()
        Session.Hangup("NORMAL CLEARING")
    End Sub
    Protected Sub HangupHook()
        Log.WriteLine(LogLevel.Debug, "AppDemo hanging up, UUID: " + Me.Uuid.ToString())
    End Sub
End Class

I copied the dll to the managed dir under mod in my FS installation. I reload FS. It loads mod_managed and the AppDemo Module as well, as you can see on console:

When I now try to execute the App from console it gives an error.

API CALL [managed(AppDemo)] output:

As you can see it doesn't work even when I type it with the Namespace in front.

Maybe someone can point me to the right direction with this.

Thanks in advance...Guido

I am playing around with FS (Windows) for one month now. First I tried using FreeSwitch.NET which is a good class library for inbound event socket. Unfortunatley it can't be used for outbound event socket. So I read the wiki back ond forth and also searched the net and found that I should use mod_managed.

So I downloaded mod_managed in source from svn and compiled it with C# 2008 Express Edition. After that I got a dll. FreeSwitch.Managed.dll and copied it to the mod dir of FS. The Problem is that I get and error when FS loads mod_managed and I don't know what I should do with that.
