I have upgraded to VS 2008 and Infragistics v8.3 NET 3.5 tools.
I have the tools installed on the toolbar.
I have upgraded a existing project from the .NET 2.0 framework to the .NET 3.5 framework using the VS 2008 upgrade wizard.
I have changed the references in my web.config and pages.config to reference the Infragistics2.... assemblies.
but when i run the page with a webpanel on it I get
Compiler Error Message: CS0433: The type 'Infragistics.WebUI.WebResizingExtender' exists in both 'c:\WINDOWS\assembly\GAC_MSIL\Infragistics2.WebUI.WebResizingExtender.v8.3\8.3.20083.1009__7dd5c3163f2cd0cb\Infragistics2.WebUI.WebResizingExtender.v8.3.dll' and 'c:\WINDOWS\assembly\GAC_MSIL\Infragistics35.WebUI.WebResizingExtender.v8.3\8.3.20083.1009__7dd5c3163f2cd0cb\Infragistics35.WebUI.WebResizingExtender.v8.3.dll'

and in the project itself i have referenced the Infragistic2.XXX.XXX.XXX.dlls
but when i run a page i get.
An individual project may reference exactly one version of NetAdvantage for .NET assemblies. By "version," this includes year, volume, CLR version, and exact version number (i.e. which release or hot fix the assemblies come from).
Also, remember that if your project uses another project as a reference, your project inherits all the references from that other project. In other words, if both projects include references to NetAdvantage for .NET assemblies, they must be for the same version.
While I don't see any "Infragistics35" references in the web.config snippet you included, the error message confirms that there is such a reference somewhere. Places to check include:
