I have a number of dtsx projects created under Visual Studio 2005.
When I try to convert the solution to 2008 it converts fine but then the .dtproj file can’t be loaded:
myProj.dtproj' cannot be opened because its project type (.dtproj) is not supported by this version of the application.
I have SQL Server 2005 installed but I got rid of Visual Studio 2005 as I am moving all my projects to Visual Studio 2008.
Reinstall the shell for BIDS. You can’t use VS 2008 with SQL Server 2005 dtsx.
