We have released version 2.3.2 of WpfDiagram. It adds support for .NET 4 and implements several customer requested features:

Support for .NET 4
The package now includes a .NET 4 version of the MindFusion.Diagramming assemblies, available in the VS2010 subfolder of the installation folder. These assemblies can also be used in applications that target the .NET 4 Client Profile. The VS2010 folder also includes sample projects for Visual Studio 2010. Version 3 of the .NET runtime is still supported.

Styling
This version enables styling of diagram items through the WPF styling system. Now DiagramItem provides a Style property, which can be set to an instance of the System.Windows.Style class. The style can contain setters for the Brush, Stroke*, Text* and Font* dependency properties that were introduced in the last release. Using the style's TargetType attribute it is also possible to define a global style in the window or application resource dictionaries for each type of node.

Miscellaneous
~ ContainerNode now provides an UpdateBounds overload that also includes links in the new node boundaries.
~ A new ZoomToRect overload can center the specified rectangle in the current viewport.
~ The MouseInputMode property of DiagramNodeAdapter specifies which control should process mouse input.
~ Fixed support for browser applications in the Internet zone.

API changes
~ The LinkStyle enumeration and the Style property of links have been renamed respectively to LinkShape and Shape.
~ The TableStyle enumeration and the Style property of tables have been renamed respectively to TableShape and Shape.
