I have added a filterConfig.yml file to my DocFX configuration. When building the documentation the builder reports the following warning:
filterConfig.yml: warning MissingYamlMime: Please add `YamlMime` as the first line of file, e.g.: `### YamlMime:ManagedReference`, otherwise the file will be not treated as ManagedReference source file in near future.
I tried to add ### YamlMime:ManagedReference as suggested but the warning is still reported.
Any idea how to fix this?
