On Friday, Microsoft released chart controls for Microsoft .NET Framework 3.5. These are re-tooled Dundas .NET chart controls which are now baked in the .NET framework. This is important because you can add the same stunning Dundas chart features to your Windows Forms and ASP.NET applications without external dependencies or licensing fees. It also minimizes your learning curve, as the Dundas controls share the same object model across technologies, e.g. Windows Forms to ASP.NET to Reporting Services.
Currently, only the Dundas chart control has made the cut to .NET. There is a sticky post at the top of the forums that has all of the links. Keep an eye on the PDC announcements today for more BI goodies.
