I keep getting this exaxt same error message when I am deploying any sharepoint blueprint silverlight2 webpart from Visual Studio 2008 or when I try to activate any sharepoint blueprint silverlight2 webpart from Site Collection Features.


I have created the XAPS library (confirmed that it is XAPS not XAPS1) and uploaded all the sharepoint blueprint silverlight2 XAPS files from their corresponding Bin directories.


All my sharepoint silverlight 2 blueprint configuration has been checked many times and everything is exactly as specified by the sharepoint silverlight 2 blueprint guidance documents.

Problem fixed.


I was creating the XAPS library from Central Administration (i.e. root level) instead of Site Collection level.
