If you just want to share your working set definition with other members on your team, it's very easy.
You will have a file containing the project-based definition of your working set. This can be imported by your team so
that they can have the same working set, as long as they have the files that it represents with the same paths.
Generally, this is probably a safe assumption for people on the same team using the same IDE.
If you want to export the actual files contained in your working set, the steps are a little different, but they make
sense once you think about it.
Note: I generally have the "Top Level Emements" of my views set to "Working Sets", so this is based on that
assumption. It is easy to toggle (View arrow menu).
This method does not export the working set definition, just the files themselves. Using both methods you could export
the working set and the files so that your team can have everything they need. These techniques are useful when sharing
files or when you want to extract a component and create a new project from it.
