If you already have a SQL Server 2008 or a SQL Server 2008 R2 instance then do not install SQL Server Denali as a named instance. If you do so then your current SSIS development environment will be broken. There is a reason there are virtual machines, I recommend using VirtualBox
With CTP1 of Denali, BIDS is still based on Visual Studio 2008, in a later version it will use the 2010 shell.
Anyway if you do install Denali as a named instance this is what happens when you try to create a new SSIS project
Here is the text
Microsoft Visual Studio
‘C:UsersDenisAppDataLocalTemptemp.dtproj’ cannot be opened because its project type (.dtproj) is not supported by this version of the application.
To open it, please use a version that supports this type of project.
