One of my customers asked me yesterday if dbdesc 3.0 supports SQL Server 2008 databases.
The answer is yes, dbdesc works just fine with SQL Server 2008 RC0 and even documents the new data types.
There is however a small issue… it won’t script tables. The current version of SMO does not support SQL Server 2008 databases and even though there is a workaround using DMO, I prefer to wait until the RTM version.
