I tried the preview upgrade on a project with the SiteSeeker module on it yesterday and most of it did go well but I have one problem that I can't figure out what it is.

We have this class

public class IntraSiteSeekerConfiguration : EPiServerSiteSeekerConfiguration
    {
        public CustomerSiteSeekerConfiguration()
            : base(new SiteSeekerServiceOverride(), 
                   new SiteSeekerServiceOverride())
        {
        }
    }

And the baseClass looks like this:

public class EPiServerSiteSeekerConfiguration : SiteSeekerConfiguration
    {
        public EPiServerSiteSeekerConfiguration(params SiteSeekerServiceOverride[] serviceOverrides);
    }

The error we get is this: (sorry for the swedish in the message)

Anyone got any clue?
