PPLs Included in SLNFILE Replacement Order

[joshj76]

Including PPLs using the slnfile method results in the PPLs being swapped in alphabetical order (due to them being stored in a set), but the order of replacement was significant in my testing.

I found that if I replaced the PPLs in the order they were created in, the build succeeded, but the build failed if I attempted to replace alphabetically.

Can a feature be added to programmatically determine the dependency order of previously created PPLs?

@joshj76 , have you tested your latest code changes with the latest main which has an attempt at solving this issue to see if it was indeed fixed or still a problem?
