Your website says that WPF 2007.2 works with .NET 3.0 AND 3.5. However the installation notes say:
All included assemblies have been built against Microsoft .NET Framework Version 3.0. You must have this version of the framework installed for the product to work.
Is the website mistaken? If not, how do you use these controls on a machine that only has 3.5 installed?
If you have the 3.5 framework installed then you have the 3.0 framework. Both the 3.0 and 3.5 framework were extensions to the CLR 2 framework. The 3.0 framework added things like WPF, WF and WCF. The 3.5 framework added things like LINQ, addin support, etc. The documentation for the 3.5 framework install indicates that it includes the 3.0 framework:

Is infragistics wpf itself is compiled against 3.0 or 3.5?
thanks

They are currently setup to target 3.0 but as I mentioned - it really doesn't matter as 3.5 was just an extension to 3.0 which was itself just an extension to the CLR 2.0. You can still use the assemblies whether you have the 3.0 framework installed or the 3.5 framework installed (since the latter includes the former).
