In my newly created VS project that is created from "React and ASP.NET Core" template, I have github actions definitions automatically created by github in %ROOT%\.github\workflows\ folder, but I don't see these files in the Solution Explorer window in Visual Studio.
I saw somewhere that it doesn't work yet if the solution doesn't contain ASP.NET Core project, but in my case, I do have an ASP.NET Core Web API project. Can someone shed some light on this?
To clarify: I mean auto finding github action files and grouping them under folder like:

How did you open the solution? Try starting Visual Studio and then use File->Open... to open the solution.
There is a known problem with "GitHub Actions" missing with opening via right-click or other means.
