Discussion:
Issue Type: <bBug</bI have a multi-root VSC workspace with three folders: A/ ./subfolderOfA In A/, there is a file and in there, there are the following settings: When I edit some file somewhere inside A/, it seems like this JSON schema file path is only properly resolved If I remove folders and from my multi-root workspace. Shouldn't this work?

Hi Unfortunately, I am not familiar with your planning process but I wanted to ask if this bug will be solved in the near future?
Sorry, I don't know when I will find time for looking at this.
It's honestly quite a shame that this feature is missing. Unless you want to modify the json file structure to include the "$schema" property you are stuck having to open the given sub-folders directly which is a significant detrement to the DX when working in multi-root workspaces.
Hi Sorry to pick this up again but, according to the motto "New Year, New Luck", is there a chance to have this and fixed soon?
It seems like relative schema path resolution does not work on Windows, even when not in a multi-root workspace. Schemas always try to resolve in rather than the workspace folder. !
Note: relative path can not be used in user settings. But they should work in workspace files, where I could reproduce the problem, thanks !
Now on macOS, unfortunately it seems like json.schemas in the workspace settings are ignored.

<img width="1605" alt="image" src="https://user-"Changing to something invalid does not result in any diagnostics being reported, either. However if I move into my user settings and change the schema path to be absolute, it works.
Now I get in the Problems view with the following setup: In a non-multi-root workspace:
I created a separate issue to investigate as the error comes from to the empty which is unrelated. If you remove the you should see that the - schema is used
To verify: clone open workspace look at the workspace settings: all files are associated with schema . Note that this is a relative path to the workspace file open both files and check that code completion gives back property . You can also click on the JSON language selector ( next to JSON in the status bar) to see the schema that is associated look at the folder setings: is associated with schema . Note that this is a relative path to the folder open both files files and check that code completion gives back property , but only when in folder1. You can also click on the JSON language selector ( next to JSON in the status bar) to see the schema that is associated
I tried to verify this using build but the schemas are not used. Here is what I see in the UI: <img width="706" alt="image" src="https://user-" please advise which build I should use for verification.
Looks like it is still not working on Windows due to to an URI encoding issue.
I tested as described in with VS Code 1.76.0 on Windows. I observed the following for and in VS Code: no schema-defined code completion is offered there is no schema offered when clicking on the language selector I then tested folder-only settings by opening VS Code to . I observed the same as above for . FWIW, describes another repro with only folder settings (not workspace settings). Is there a known workaround to get validation working using on Windows for 1.76.0?
the fix for Windows is coming:
is now also fixed (and verified)
