title: Simple c# WPF TreeView
body: <p>from my Forms Windows App I'm used to build a TreeView like this</p>
  
  <pre><code>treeView1.Items.Add("Result");
  treeView1.Nodes[0].Items.Add("Child 1");
  treeView1.Nodes[0].Items.Add("Child 2");
  treeView1.Nodes[0].Nodes[1].Items.Add("Grandchild");
  treeView1.Nodes[0].Nodes[1].Nodes[0].Items.Add("Great Grandchild");
  </code></pre>
  
  <p>How am I supposed to do this in WPF? I'm confused with all the samples in the web!</p>
  
  <p>Thanks!</p>
