NetOffice - for professional COM Addin developers

I am using NetOffice v1.7.3 as a Nuget package in my c# application in order to perform Visio automation tasks.

The below example shows how I try to call an IVPage object's DropMany() method:

         double[] dropCoords = new double[] { 1, 2, 3, 4 };
         object[] dropMasters = new object[] { masterShape.ID, masterShape.ID };
         short[] droppedObjectIDs = new short[dropMasters.Length];
         page.DropMany(dropMasters, dropCoords, out droppedObjectIDs);

Executing the above code throws the below exception:

Exception has been thrown by the target of an invocation..Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH)).

I am wondering if I am calling this method with the wrong parameters or is this a bug.

Thank you.
