Create a simple polyline, a closed polyline. And a Sine curve in code.

//File:Window.xaml.cs

using System;
using System.Windows;
using System.Windows.Media;
using System.Windows.Shapes;

namespace WpfApplication1
{
public partial class Polylines : Window
{
public Polylines()
{
InitializeComponent();
for (int i = 0; i < 70; i++) { double x = i * Math.PI; double y = 40 + 30 * Math.Sin(x / 10); polyline1.Points.Add(new Point(x, y)); } } } } [/csharp]

Polyline corner is cut off (beveled) because the miter limit is set to 1
