Issue when using edges (WPF) about graphx HOT 1 OPEN

            LogicCore logicCore = new LogicCore

                Graph = BuildGraph(data),

            param.Direction = LayoutDirection.TopToBottom;

            //This property sets vertex overlap removal algorithm.
            //Such algorithms help to arrange vertices in the layout so no one overlaps each other.

            //This property sets edge routing algorithm that is used to build route paths according to algorithm logic.
            //For ex., SimpleER algorithm will try to set edge paths around vertices so no edge will intersect any vertex.

            //This property sets async algorithms computation so methods like: Area.RelayoutGraph() and Area.GenerateGraph()
            //will run async with the UI thread. Completion of the specified methods can be catched by corresponding events:
