RichardAubin Is it possible to suppress these errors? They are internal to WordPress core, and I really don't feel like going and fixing their code just to not have these errors show up in my IDE.
JakubMisek RichardAubin I have a quick workaround for now; in Tools / Options, you can simply turn off errors for non-user files: This ignores errors in wp-include and wp-admin folders in the root of the project.
JakubMisek RichardAubin There is an error in .editorconfig and Visual Studio quietly ignores it. The section [*.php] is duplicated there. Once you put the directives under single [*.php], it starts working. There must be no duplicate [*.php] sections.
JakubMisek This issue with duplicate [*.php] section will be fixed in the next update. Workaround for now is to remove the duplicate [*.php] line from .editorconfig
