Type of issue

Missing information

Description

On "Unix" platforms FileVersionInfo only looks at managed metadata, while on Windows it uses GetFileVersionInfoEx.

The documentation mentions that the "properties are based on version resource information built into the file", and that "Version resources are typically specified in a Win32 resource file, or in assembly attributes." - but it does not mention that the "Unix" platforms only work on managed executables and returns the values found in the managed metadata, unlike Windows which looks at the Win32 resource data.

(This was earlier brought up in an issue on the runtime repository which was incorrectly closed after an unrelated fix, but the difference should be documented.)
