I installed SQL Server 2005 Beta 2 on the vbCity web server machine (as new instance on the top of the default instance production SQL 2000). Some of the new scripts I'm putting together for both vbCity.com and DevCity.NET will be using SQL 2005 backend.
I absolutely love the new things SQL 2005 has to offer especially SQL cache, cache invalidation, XML data type and SQLCLR (managed SQL stored procedures). I already played with the latter and thinking about writing an article on that.
