Format On Type doesn't work

[interpol-kun]

Issue Description

Editor option "Format on Type" does not work. Typing is ignored and formatting could be applied only via Save or Paste (if they are toggled on).

Steps to Reproduce

Install fresh VSC, toggle on "Format On Type" option in settings, install C# extension from the marketplace. Open up the C# solution, start writing any method with curly braces. After you hit enter it wont format the braces. Hit Ctrl+S and formatting will be applied.

Here is the GIF of that behaviour. (I opened curly braces, pressed ENTER and then pressed CTRL+S -- this is the moment the formatting was applied).

More to say, I have reproduced the same error on both Ubuntu 19.04 and Windows 10, on both Insider and Stable VSC builds.

I did a fresh installation of VSC and the C# extension (I removed any settings and config files associated with VSC and extensions). It didn't help.

Expected Behavior

Code formatting should be applied on typing.

Actual Behavior

Code formatting only applied on Save or Paste

I'm seeing this behavior with VSCode 1.40 and C# Extension 1.21.6

[mletterle]

I'm guessing this behavior is essentially a duplicate of #1591 would be fixed by #1906

[DanJ210]

I'm getting this behavior also. No formatting extension is formatting unless I do a save.

[Ashen-Vaults]

Also getting this. Any update when this fix will be released?

[dawsno]

I'm also getting this behavior with the latest version of vscode and the c# extension
