    What is that NavisionInvoice.IInvoice doing?

    Also this looks like the variable is declared wrong as though the actual interface types have been chosen and this is why you can not create instance of type interface IInvoice.

    If anything I would expect to see the variable declared as NavisionInvoice.Invoice

    NavisionInvoice.IInvoice is an automation dll written in C# consuming a WCF service.
    The interface is called IInvoice.

    But that means that the C# automation has not been written correctly.

    Is this similar to the problem you were getting with this post?

    Your variable should not be declared of type IInvoice...

    Can you post a screenshot of the variable definition in NAV so we can see what is exposed by the automation...
