VS Code Formats my Code when hitting ENTER.

[SimonCahill]

Issue Description

For a few updates now, VS Code has been doing this stupid thing, where it reformats my code to use the Microsoft/Allmann styling.

If I wanted to an inferior bracing style, I would. VS Code is, specifically for this reason, configured that it DOESN'T reformat my C# code.
It's not only frustrating, but infuriating behaviour; don't force an inferior coding style onto us.

Steps to Reproduce

Write C# code. Hit enter. Braces placed using K&R style will be moved to Allman style.

Expected Behavior

That it leaves my braces tf alone.

Actual Behavior

It doesn't.

Config

{
    // snip
    "omnisharp.useEditorFormattingSettings": false,
    "csharp.format.enable": false,
}

Thanks for sharing, this does seem like an unfortunate side-effect of a change to improve typing responses in some cases. We are collecting feedback for this here though: #8316 . There is also a workaround to disable it here. Hope that helps!

Resolving this as a dupe.

@AbhitejJohn I've since figured out that a previously disabled configuration was re-enabled after the update.

How is that a "side-effect"? When will VS Code add support for formatting C# code? It seems silly that you're (rightfully) pushing VS Code, yet the support for the most basic features is lacking.
Even the suggested "editor-config" files don't do anything of the sort.
