SQL Server 2008 compatibility with SQL Server 2005

Question

What is the best way to use SQL Server 2008 as a development database, but ensure that the database is compatible with SQL Server 2005?

Answer 1

Don't forget that there are also behavioral differences between the two versions, and something on 2008 may perform differently (and insufficiently) than 2005 all other things equal - this will obviously depend on a lot of factors about your data and application.

You're better off developing against the lowest common denominator and testing against the newer versions.
