This topic will give you guidelines for porting applications developed with version 3.0 to the new version.
In version 4.0, three new assemblies were added to the chart control:
Xceed.Chart.GraphicsCore.dll – core functionality for the graphics engines
Xceed.Chart.Graphics2D.dll – GDI+ rendering engine
Xceed.Chart.UIControls.dll – user interface controls
The assembly Xceed.Chart.GLCore.dll is renamed to Xceed.Chart.GraphicsGL.dll.
The following is the full list of assemblies of Xceed Chart for WinForms 4.0:
Xceed.Chart.Utilities.dll
Xceed.Chart.GraphicsCore.dll
Xceed.Chart.Graphics2D.dll
Xceed.Chart.GraphicsGL.dll
Xceed.Chart.UIControls.dll
Xceed.Chart.Standard.dll
Xceed.Chart.Core.dll
Xceed.Chart.dll (contains the Windows Forms control)
Xceed.Chart.Server.dll (contains the Web Forms control)
Xceed.Chart.DataManipulation.dll
We recommend that you take the following steps to update your project:
Make a backup copy of the application’s source code.
Remove the chart control from the forms of your application.
Uninstall the old version of the chart control.
Install version 4.0 of the chart control.
Add the new control to the Visual Studio toolbox and then place it in your application’s forms. If a problem occurs while inserting the control, you can manually add the chart control assemblies to the references of your project and then try again to place the control on the form.
In order to compile the project you will most probably have to make some changes to the source code because of the altered programming model of the chart control. The following topics describe these changes in detail to help you port the source code of your application.
All enumerations previously defined in Xceed.Chart.GLCore.dll are moved to Xceed.Chart.GraphicsCore.dll, and some of them are also renamed. The namespace Xceed.Chart.GLCore no longer exists, so in your source code you have to change “using Xceed.Chart.GLCore;” to “using Xceed.Chart.GraphicsCore;”
The following table describes the changes in regard to enumerations.

| Xceed.Chart.Server.ResponseType | The enumeration does not have HTMLImageMapPostback value | The HMTLImageMap response type now encapsulates all the functionality needed to produce postback. |
The following table describes the changes made in version 4.0 with regard to classes. The major change is that interactivity operations and some other classes are moved from the former Xceed.Chart.GLCore.dll (Xceed.Chart.GraphicsGL.dll in version 4.0) to the new assembly Xceed.Chart.GraphicsCore.dll. The namespace of the classes should be changed accordingly in your application source code.
