Visual Studio 17.3 new features not working - is there a solution?

Question

Here are some new features from version 17.3 (which is now supposed to be the stable edition, not in preview anymore) according to Microsoft:

• Collapse #regions on file open
• Collapse usings on file open

Both simply don't work as well as this one:

Audio Cues in the Editor

Which is not present where they say it is. I.e. in "Preview Features" under Environment.

I'm running Visual Studio 17.3 on Windows 10 with the latest updates.

Any way to fix these problems?

(Maybe it has to do with the fact that the release notes for the stable build (see link above) still show the "pre" icon, and they even have the box titles "Important" saying it's a preview release.)

Answer 1

Check first if this is related to the following prerequisite:

To enable audio cues, head to Tools\Options and look for "Preview Features" under Environment.

Without that, those new options might not work.

See "Listen Up, Visual Studio has a new feature you need to hear about!"

Aug. 2022: The option was in 17.3 preview 2, but was reported missing in 17.3 final.
This is currently being investigated.

Nov. 2022: this is resolved with VS 17.4.

The collapse options are from PR 60743, with the options panel being:

It's worth noting that VS remembers the outlining state for all files so if you change the checkbox you should delete the .suo file, or the .vs directory, and then check what happens when you open a file.
