this morning i try to write a simple test application on my laptop(xp-sp2+cassini+sqlexpress+vs2008) but i got the same exception. May be it's about my regional settings (turkish). we have some incompabilities about case changing of char "i". check here for details.

http://www.i18nguy.com/unicode/turkish-i18n.html

is there any string case change prosedures in openaccess's source ?

Hello onur,
Yes there is indeed problem with the regional settings. The workaround is to resolve the scope in the following way:

Database db = Database();
            CultureInfo old = System.Threading.Thread.CurrentThread.CurrentCulture;
            // Workaround:
            System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.GetCultureInfo("en-US");
            try
            {
                IObjectScope newScope = db.GetObjectScope();
                return newScope;
            }
            finally
            {
                System.Threading.Thread.CurrentThread.CurrentCulture = old;

            }

So if you are using for example IObjectScope scope = ObjectScopeProvider1.GetNewObjectScope(); You should paste the above code into the GetNewObjectScope method into your ObjectScopeProvider1 class. 
The issue has been worked on and in the next patch release a fix for this will be included.
Please do let us know if you face any further difficulties.
