I used to be able to just build a DocFX page both locally and on gh-pages. But since recently, I keep getting a warning message: No .NET API detected for project. This happens both locally and on gh-pages, even when I install a fresh DocFX according to the Quick Start Guide and call docfx docfx.json --serve on the default file.
Does anyone know what the issue is and how I might be able to solve it?
