    How to construct a line symbol from a stroke
    CIMStroke stroke = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.BlackRGB, 2.0);
    CIMLineSymbol lineSymbolFromStroke = SymbolFactory.Instance.ConstructLineSymbol(stroke);
    
    How to construct a multilayer line symbol with circle markers on the line ends
    //These methods must be called within the lambda passed to QueuedTask.Run
    var lineStrokeRed = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.RedRGB, 4.0);
    var markerCircle = SymbolFactory.Instance.ConstructMarker(ColorFactory.Instance.RedRGB, 12, SimpleMarkerStyle.Circle);
    markerCircle.MarkerPlacement = new CIMMarkerPlacementOnVertices()
    {
      AngleToLine = true,
      PlaceOnEndPoints = true,
      Offset = 0
    };
    var lineSymbolWithCircles = new CIMLineSymbol()
    {
      SymbolLayers = new CIMSymbolLayer[2] { markerCircle, lineStrokeRed }
    };
