Syntax-coloring is not applied or removed when changing Build Action from None to Compile and vv
Since out-of-project files are no longer colored (inverse to this issue #1977 may have you believe), there now appears to be a small issue with that: it doesn't work when the project has dirty state, it only works if you compile.
Repro steps
Basically:
- Open any project *.fs file
- Change the Build Action to
None - Result: no effect
You can try to close/reopen the file, but still no effect.
The inverse is also true: change from None to Compile will not color the file.
Expected behavior
Since this change was applied (#1977, possibly it's VS2017, not just Visual F#), this expected behavior is different now: it should remove the coloring, or inverse, it should add the coloring back.
Actual behavior
Syntax coloring, or removing of coloring is not applied.
Known workarounds
Recompile the project.

F# 4.0 and F# 4.1 with VS2017 15.3.1.0. Also observed in recent nightlies.
A small issue, I know, but I thought to better have it reported in case somebody is working on something in this area.
Just checked with latest builds, but this still happens. Rebuild is still necessary. Seen in Visual Studio 15.6.
Behavior has changed again. Right now (in VS 2022 Community, Version 17.8.6), if the build action is set to None, it will still syntax-color the file. It also appears to process the opens and report syntax and type errors. This may result in performance degradation.
This is incorrect behavior: if the build action is None, errors should not be reported (note that regardless, build succeeds).
