***Disclaimer: This information applies to Visual Studio 2010 Beta 1 only.***
In the previous version of the VS SDK, when we create an Isolated Shell project, there is a command to specify Shell Dependencies:
When we compile the project, those dependencies plus any pkgdef file are being copied to the \PackagesToLoad subfolder.
Now is VS10, the Shell Dependencies command is gone and the way to add dependencies is via the References button. (which seems more natural to me)
Another change is that the PackagesToLoad subfolder was renamed to “Extensions” to be sync with the full IDE extension naming thing.
