Note: steps to reproduce and erroneous output copied verbatim from #1720, as per #1720 (comment).

Steps to reproduce

• Under VS2019, create a new project "Windows Forms App (.NET Core)"
• In Program.Main(), type var folder = Environment.CurrentDirectory;
• Right-click on CurrentDirectory > "Open code in ILSpy"

Erroneous output

You land on the method with a warning "This assembly is marked as 'reference assembly':

In case it helps, the assembly in question shows the following header:
