Hello,
I'm using the Infragistics NetAdvantage for WPF 2008 Vol. 2 on a 64 bit XP install with Visual Studio 2008 V 9.0.30428.1 SP1Beta1. I actually just realized that I was running a beta1 SP1 of Visual Studio, I'll work to get the latest release SP1 and see if that helps, in the meantime, I'll describe my problem in case anyone else is experiencing it.
Previously, I had .NET Framework 3.5SP1 (Beta) installed, and upgraded to the "non beta" 3.5 SP1. Apparently, they moved the class "System.Windows.NameScope" out of the assembly "WindowsBase" and into the "PresentationFramework" assembly.
I'm certain this is the cause of this issue, but I'm not able to find the fix. I'm going to try uninstalling VS SP1 Beta1 and installing the full SP1 and report back.
Glad to hear the problem was resolved! Thanks for updating us and letting us know the RTM version of the VS 2008 SP1 worked for you.
Okay, my mistake. Updating to the proper SP1 of Visual Studio resolved the problem. Thanks for reading. :-)
