1. Open your project.

2. Close all forms.

3. Remove Flowchart.net.dll from the project references list.

4. Open the form that contains the FlowChart control in the code editor (use the View Code from the form file context menu).

5. Find and remove the declaration of the Flowchart member field from the form.

6. Go to the form's InitializeComponent method.

7. Remove the FlowChart constructor call.

8. Select and cut to the clipboard the FlowChart instance initialization code found in InitializeComponent.

9. Paste the initialization code into a text file.

10. Remove the Controls.Add call that adds the FlowChart instance to the form.

11. Save the form code file.

12. Now you can open the form in design mode. Do so.

13. Add the MindFusion.Diagramming.dll and MindFusion.Diagramming.WinForms.dll to the toolbox.

14. Drag a Diagram from the toolbox to the form.

15. In the property browser rename the Diagram instance so that it has the same name as the old FlowChart instance.

16. Drag a DiagramView from the toolbox to the form.

17. Select the DiagramView and in the property browser select the Diagram property, drop down the combo box and select the Diagram instance you have added above. If the combo box is empty, close the form and open it again so VS can find the Diagram instance.

18. Rebuild the project - there might be a few hundred compilation errors, depending on how much of the Flowchart.NET API you are using.

Next, fix the "type XYZ not found" errors.

Many types have been moved from the MindFusion.Diagramming.WinForms namespace to MindFusion.Diagramming. Add an using/imports MindFusion.Diagramming directive at the top of the file, or remove the "WinForms" part where necessary if you prefer using fully-qualified type names.

A good way to quickly fix these errors is to use the Replace in Files command, with the "Whole word" and "Case sensitive" options enabled. These are the most commonly used FlowChart.NET types that have been renamed:

ChartObject -> DiagramItem
Arrow -> DiagramLink
Node -> DiagramNode
Box -> ShapeNode
Table -> TableNode
ControlHost -> ControlNode
ShapeTemplate -> Shape

I'll post a more detailed table below. For now leave EventArgs-related class names alone.

There aren't Diagram.CreateXYZ() methods, but there are Diagram.Factory.CreateXYZ() ones.

This is the recommended way to create items now:

ShapeNode node = new ShapeNode();
node.Bounds = new RectangleF(...);
node.Shape = Shapes.Rectangle;
diagram.Nodes.Add(node);

This makes it possible to use the same code for creating instances of custom node or link types. Though if you are using the standard types, you can still use the diagram.Factory methods for brevity.

There aren't FindBox, FindTable, FindControlHost methods, but just FindNode. You must use refection to determine what type of node has been found. The same goes for GetBoxAt, GetTableAt, GetControlHostAt -> now there is GetNodeAt method.

The FitSizeToBox/Text methods have been renamed to ResizeToFitBox.Text. The FlowChart.FitObjsToDoc is now called Diagram.ResizeToFitItems.

replace loops of this kind -

foreach (Box b in flowchart.Boxes)
{
  ...
}

with

foreach (DiagramNode n in diagram.Nodes)
{
  ShapeNode b = n as ShapeNode;
  if (b == null)
    continue;
  ...
}

The behavior, mouse cursor, printing and clipboard related properties and methods are now members of the DiagramView class, either because they are used mostly for interaction, or because they reference System.Windows.Forms.

The Diagram class contains the diagram data and some default-value properties. The MindFusion.Diagramming.dll where Diagram is defined can be used instead of the Webchart.dll in the WebApp sample scenario, since it does not reference Windows Forms. Webchart.dll is not supported anymore.
