Vista's done!  Finally :)

For those who have tried the beta or an Release Candidate, you'll notice a few issues and problems with Visual Studio 2005.

Being a brand new operating system on the bleeding edge, there have been several changes made, especially to secure your machine from malware.  Those changes and lock downs will affect previously released software.  When installing VS, you'll notice an application compatibility dialog pop up.  It's just a warning that not all things may work properly.  It'll appear a second time when SQL Server Express is being installed by VS.

For now, the workarounds for VS issues is documented here:

For SQL Server Express issues, please install the latest SQL Server Express (SP1 or SP2 when it's available).
