I have just converted one of my VS 2005 projects to VS 2008. We have a full (not trial) .Net Advantage 2007 license. When I go to buid the project in VS 2008 I get following exception for all of the Infragistics assemblies:
Error 12 Exception occurred creating type 'Infragistics.Win.UltraWinEditors.UltraPictureBox, Infragistics2.Win.UltraWinEditors.v7.1, Version=7.1.20071.1071, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' System.ComponentModel.LicenseException: NetAdvantage For Win Forms Trial Period Expired C:\Users\Development\Documents\Visual Studio 2008\Projects\xxxx
Why? How cab a non trial license expire?
Well, I ran .Net Advantage installer again at which point it prompted me to upgrade form a trial version(?) I typed in my lic key and everthing is working now.
NetAdvantage 2007 Volume 1 is not supported in the Visual Studio 2008 IDE. Since no testing has been done with 7.1 and VS08 they may be issues such as this when using that combination. You could try to rerun the installer for NetAdvantage so that if something is awry with the installation it would repair such issues. You should also try going through the process of recreating the Infragistics toolbox in VS08 and rereferencing the Infragistics assemblies. This is typically done for upgrading from one version of Infragistics to another or when upgrading from a trial version to a licensed version.
If none of this works, you may have to upgrade if you want to use Visual Studio 2008 with our toolset. Even if it did work there are some issues regarding the design time behavior that you will likely face.
