I just installed SQL Server Express 2008 because of intellisense feature. It worked at first but than it stopped working. Looking for the option to check and later consultin
there is code in the SQL Server 2008 database engine that supports the intellisense feature in Management Studio 2008.
No there isn't. You're entirely wrong, and should be slapped with a wet fish.
All it is doing is interrogating the various INFORMATION_SCHEMA virtual tables to do discovery. The reason they disabled it against prior versions is that theoretically it might encourage you to use a syntax that is only valid against 2005, but lots of people were using it with 100% success. Of course the real reason they disabled it is that it reduced one advantage of upgrading your servers to 2008 (which is where they make the real money).
