A WPF version of Flowcharter is not available yet. Drag-and-drop of images is shown in the FCDemo sample:

void diagram_Drop(object sender, System.Windows.DragEventArgs e)
  {
       Point p = e.GetPosition(diagram);
       Point pt = diagram.ClientToDoc(p);
           
       if (e.Data.GetDataPresent(typeof(Image)))
       {
               Image i = (Image)e.Data.GetData(typeof(Image));
               ShapeNode b = diagram.Factory.CreateShapeNode(pt.X, pt.Y, 10, 10);
               b.Image = i.Source as BitmapSource;
               b.ResizeToFitImage();
               b.Transparent = true;
       }
       ...
}

I hope that helps,

In the project properties window, Debug tab, clear the "Working directory" text field content.

Try this -

void BuildTree(DiagramNode diagramNode, TreeViewItem treeItem)
{
	foreach (DiagramLink link in diagramNode.OutgoingLinks)
	{
		DiagramNode childNode = link.Destination;
		TreeViewItem childItem = new TreeViewItem();
		childItem.Header = (childNode as InplaceEditable).GetTextToEdit();
		treeItem.Items.Add(childItem);
		BuildTree(childNode, childItem);
	}
}

void ToTreeView(DiagramNode rootNode, TreeView treeView)
{
	TreeViewItem rootItem = new TreeViewItem();
	rootItem.Header = "root";
	treeView.Items.Add(rootItem);
	BuildTree(rootNode, rootItem);
}
 

If you are using TableNodes whose ConnectionStyle is set to Rows or Both, you might also have to iterate over the OutgoingLinks of each table row.

Can't you implement the zooming function by changing the table.Bounds.Width and showing / hiding the links between the two tables?

You could let users collapse the table to its caption area and expand it back by double-clicking, for example:

private void diagram_NodeDoubleClicked(object sender, NodeEventArgs e)
{
	TableNode table = e.Node as TableNode;
	if (table != null)
	{
		// Check if the caption has been clicked
		if (e.MousePosition.Y - table.Bounds.Y < table.CaptionHeight)
		{
			// The caption is clicked -> Expand / Collapse table
			bool expanded = false;
			if (table.Tag == null)
			{
				expanded = true;
			}
			else if (table.Tag is float)
			{
				if ((double)table.Tag == 0)
					expanded = true;
			}
			else if (!(table.Tag is double))
			{
				expanded = true;
			}

			if (expanded)
			{
				table.Tag = table.Bounds.Height;
				Rect rc = table.Bounds;
				rc.Height = table.CaptionHeight;
				table.Bounds = rc;
			}
			else
			{
				Rect rc = table.Bounds;
				rc.Height = (double)table.Tag;
				table.Bounds = rc;
				table.Tag = null;
			}
		}
	}
}
