Don't know if you have heard this announcement yet. If you are an MSDN subscriber you can download the release candidate for Visual Studio 2005. I got my copies last night and am looking forward to seeing what's been fixed. One area I'm particularly keen on testing is performance. It should be getting close -- only two month until the release.
Also available is the SQL Server September CTP. Rumor has it that these versions of SQL Server and Visual Studio are compatible. I'll be installing them tonight and will let you know what I find out.
Go get yours today.
