+            The LINQ expression tree may contain unwanted type conversions that were not in the original expression written by the user. For example,
+            <c>list.Where(someChar => someChar == 'A')</c> becomes the equivalent of <c>list.Where(someChar => (int)someChar == 55)</c> in the expression
+            tree. Converting this directly to a HQL/SQL statement would yield <code>CAST(x AS INT)</code> which does not work in MSSQLSERVER, and possibly
+            other databases.
