reload not triggered when profiles.json is a symlink

[newgene]

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.175]
Windows Terminal version (if applicable): 0.2.1715.0

Any other software?

Steps to reproduce

I tried to keep profiles.json saved in my OneDrive, so I created a profiles.json symlink as the following:

DEL /Q %LocalAppData%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState\profiles.json
mklink %LocalAppData%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState\profiles.json %ONEDRIVE%\Windows\conf\WindowsTerminal\profiles.json

Expected behavior

It should work exactly like the actual profiles.json file: any modification will trigger the reload of the app.

Actual behavior

Windows Terminal works fine with the settings loaded from the created symlink, but when I modify the file content, it won't trigger any reload of the Terminal app. I have to close and relaunch the app in order to apply the modified settings.

So, here's the weird thing about file modifications. We can't subscribe to know when a file has been changed -- we must subscribe to know when its directory changed. The risk in following the symbolic link is that we will probably start listening for file changes in somewhere crazy (with a high event volume) like the user's home directory. ☹️

Understand.

I just gave another try with the "hard link" instead of "symbolic link":

mklink /H %LocalAppData%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState\profiles.json %ONEDRIVE%\Windows\conf\WindowsTerminal\profiles.json

It works as expected, so it's not an issue for me anymore.
