Rider apparently creating superfluous .meta files

[Kylotan]

Since a recent upgrade, I've found that sometimes I am getting a bunch of meta files created for files outside the Assets directory and that should not have meta files. These are mostly for csproj files. I just have to keep deleting them.

I can't 100% verify that it is Rider and not Unity causing this, but:

1. It's only happening to me on this project - everyone else uses Visual Studio
2. It only happens when Rider is in focus, and when it's active - I believe I saw it say "synchronising project" at the bottom, before flashing up the 'do you want to add this to Git?' dialog

It's probably worth noting that our repository contains both standard Unity projects and a packages directory, and maybe this is confusing Rider and making it think the root is further up than normal.

@Kylotan What is your Rider version and Unity version? When this issue happens again, please list here paths of those meta files. A screenshot may help.
I tried to reproduce, but no, it doesn't happen.
Feel free to reopen the issue.

Sorry, should have remembered those details.

• Unity 2019.2.1f1
• Rider 2019.3.1

Can't share full paths due to client confidentiality but here are some examples of meta files that appeared in the directory that contains Assets.

Our team is experiencing the same issue. It happens on both Windows and macOS. Worst of all, the Rider plugin even causes the meta files to get created outside the folder of the repository.

Example folder structure:

• MyRepo
  • stylecop.json
  • UnityProject
    • MyCode.csproj
    • Assets
      • Actual files that should have meta files

Meta files get created for:

1. MyRepo
2. stylecop.json
3. MyCode.csproj

Solution explorer shows this:

Can you try reproducing it in a git repo where the Unity project is one folder down and there's a stylecop JSON file in the root of the git repo?

Versions:

Reproduced, thank you!
