Infinite Guid Changes because of Symlinks

Scene Management


Reproduction steps:
1. Open project attached (
2. Setup Symlink.
- Open cmd with administrator rights.
- Go to "Project"\Assets\ComScore-iOS-SDK-master\comScore\ComScore.framework
- run this code line: "mklink /D Test Versions"
3. Go to Editor and check the console.
4. If the console is clear, go to "Assets" and use "Reimport All".

Expected result: There will be no warnings due to symlink.
Actual result: Warning appear like "The GUID for ... is already in use by...".

Notes: if you use a symlink to a file directly, everything goes ok, but if you use a symlink to a folder, it shows these warnings (and recreate the guid, etc.). It only happens on 5.6+

Reproduced on: 5.6.0a2, 5.6.3p2, 2017.1.0p5, 2017.2.0b9, 2017.3.0a6

    Unity needs to be able to handle iOS Frameworks, we need to reopen this issue.

    Does whoever marked this as Won't Fix understand the bug? The GUID for these assets changes *every time you give the Editor focus*. It makes clean commits almost impossible.

    Additional information: This occurs with iOS Frameworks which typically use these sorts of symlinks to reference "Current" from a set of contained libraries etc. As such it's going to occur for a lot of the plugins that support iOS and contain the prescribed Apple frameworks.
