Yeah, a note on that - when I was looking at that I realized that
ApplicationData and LocalApplicationData have the wrong semantics on
Linux. The former maps to "config" and the latter maps to "data",
instead of the remote/local distinction. Because of that, I avoided
using them, and implemented the XDG spec directly.

I considered that, but I think my way makes it clearer to the user
that old profiles still exist and can be removed. It also implies that
we have versioned profiles, rather that a profile with versioned data.

This is a minor use case IMO and probably not worth complicating the
UI. However, by removing MonoDevelopProperties.xml from the target
profile, you can force a migration.

Something I didn't implement support for is for migrating the user
data of addins that are installed after MD is first run, but this
would be easily fixable by keeping a list of migrated addins in the
properties store and checking loaded addins against it.

It might be worth thinking about a GUI in preferences for deleting old
profiles and clearing caches.
