http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspxThis is probably blatantly obvious to most people, but I've seen some confusion on this topic over the last couple of days, so documenting it is probably no great disaster. Some people aren't clear about how you install SQL Server 2005 ("Yukon") Betaen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspx#217638Fri, 20 Aug 2004 19:31:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:217638Mehran NikooYeap, I had to uninstall .NET Framework Beta that came with Visual Studio 2005, but didn't touch Visual Studio 2005 at all. Now everything is perfect :)http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspx#217712Fri, 20 Aug 2004 17:51:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:217712Jeffrey Palermousing VS 2005 Beta 1 and Yukon Beta on the same machine - level 100http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspx#217770Sat, 21 Aug 2004 00:57:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:217770Anatoly LubarskyYes, it is true, you have to uninstall the .net framework.http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspx#219694Wed, 25 Aug 2004 03:42:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:219694David CobbAnyone on the bleeding edge installed VS2005 Beta and SQL 2005 Beta on Longhorn successfully?http://blogs.msdn.com/tims/archive/2004/08/20/217633.aspx#219731Wed, 25 Aug 2004 04:42:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:219731Tim SneathIt depends which release of Longhorn you're talking about, David. The PDC build of Longhorn matches the PDC technical preview build of Whidbey. But for the most recent build of Longhorn (the WinHEC one), you have to use the command-line tools and the Longhorn SDK as the Visual Studio build wasn't generally released. <br> <br>I've heard some people who have done it, but it's not recommended to install Yukon on Longhorn at this stage. <br> <br>Hope this helps, <br> <br>Tim
