I am very happy to announce the first public CTP of Microsoft Expression Web Designer!
Also on Wednesday last week, Developer Division released the May 2006 CTP for the .NET Language Integrated Query (LINQ) Project. Check out a conversation with Anders Hejlsberg about the May 06 preview of LINQ and Scott Guthrie's post on using LINQ with ASP.NET.
Update: Looks like the install file for EWD is currently corrupted... I tried unzipping the EXE and I get "Extracting EWDWW.cab" CAB file WebDesigner_setup.exe is corrupt... I just emailed Wayne Smith, who incidentally is coming down for Tech.Ed to report the problem.
