    Modify a point symbol created from a character marker
    {
        //create marker from the Font, char index,size,color
        //Note: Needs QueuedTask to run
        var cimMarker = SymbolFactory.Instance.ConstructMarker(125, "Wingdings 3", "Regular", 6, ColorFactory.Instance.BlueRGB) as CIMCharacterMarker;
        var polygonMarker = cimMarker.Symbol;
        //modifying the polygon's outline and fill
        //This is the outline
        polygonMarker.SymbolLayers[0] = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.GreenRGB, 2, SimpleLineStyle.Solid);
        //This is the fill
        polygonMarker.SymbolLayers[1] = SymbolFactory.Instance.ConstructSolidFill(ColorFactory.Instance.BlueRGB);
        //create a symbol from the marker 
        //Note this overload of ConstructPointSymbol does not need to be run within QueuedTask.Run.
        var pointSymbol = SymbolFactory.Instance.ConstructPointSymbol(cimMarker);
    }
