.NET Assemblies

I'm trying to use a .NET DLL in WINDEV 12

Following code works perfect in VB2005:

Dim gXMLRouter As Coda.Xml.Router.XMLRouter  ' Declare XMLRouter Object
Dim sToken As String                         ' Declare Token String Object
gXMLRouter = New Coda.Xml.Router.XMLRouter() ' get Instance from XMLRouter Object
sToken = gXMLRouter.Authenticate("INSTALL", "OAS", "AVIABEL")

However when used in WINDEV 12

gCODAXMLRouter is XMLRouter dynamic
gToken is string
gCODAXMLRouter = new XMLRouter()
gToken = gCODAXMLRouter:Authenticate("INSTALL","OAS","AVIABEL")

The following error is generated:

Error at line 5 of Initialization of Main process.
Unable to invoke <Authenticate(System.String,System.String,System.String)> method of <String> type

The .NET assembly has been defined in the project through workshop and all conditions in setup for .NET are done.

Does someone have an idea to solve this problem?

Thanks in advance.
