Infragistics.Win.AppStyling.StyleManager.Load(@"..\..\..\..\..\Lib\Office2007Blue.isl");
Were you able to build an installation for your application? The hotfix did not upgrade the version of the Infragistics2.Win.AppStylistSupport.v8.3 assembly and it is still dependant on the 1009 versions of the assemblies.
When I deploy my application that uses styling with local assemblies it crashes. I'd rather not deploy two sets of assemblies and put them in the GAC but I'm not sure how to resolve this.
Apparently i had missed one of the assemblies in my project and it was still using the old one....it works now after upgrading...
