dotnet
C# code formatter ignores extension setting (always on)
Type: Bug
Issue Description
C# codes are auto-formatted even when csharp.format.enable (and other formatter related settings) are disabled.
The issue only occurs since version 2.69.25, and should have nothing to do with C# Dev Kit.
Steps to Reproduce
Install 2.69.25 or newer of the extension. You don't need C# Dev Kit.
Turn off csharp.format.enable (and maybe the vscode formater settings).
Edit a csharp file in a dotnet project.
Expected Behavior
Code should not be formatted when csharp.format.enable = false.
Actual Behavior
Is formatted even if so.

We started shipping the extension with formatOnType enabled for C# files. This improved the typing experience in certain cases (pressing enter after an opening brace for instance).
As a workaround while we collect more feedback about this change, you can use the query formatOnType @lang:csharp in Settings to disable it. Or, if you feel more comfortable editing the settings.json directly, you can add the following.
"[csharp]": {
"editor.formatOnType": false,
},
@JoeRobich should we potentially rename the csharp.format.enable setting? It is only applicable to O# (and is in the O# category). But maybe we should rename to omnisharp.format.enable?
Probably need to deprecate it and the semanticHighlight.enable options. Now that there are ways to configure options per language.

I've lost some hairs as they were being pulled out because of this change and I could not figure out what was triggering a whole file auto format once setting this to false the file stopped changing on every hit of new line. Thanks for the workaround!

I just lost an hour finding this. Thanks for nothing shipping an utter troll of a feature. 🤬
I had editor.formatOnType disabled forever, since it's a major annoyance.
An extension adding a language-specific override, overrides that user-preference.
So now I had to override the override. Great.
And literally no decent signaling that this was added. Or that this even can be a thing for VSCode!
I take it the team that decided on this is unaware of the term 'selector specificity wars' in the context of CSS? If so - I'd encourage them to look it up. Might be a good warning for why you shouldn't do stuff like this.

This was working for me at some point, but not anymore. I have thrown literally everything at the wall and nothing is sticking:
"editor.formatOnPaste": false,
"editor.formatOnSave": false,
"editor.formatOnType": false,
"[csharp]": {
"editor.defaultFormatter": null,
"editor.formatOnSave": false,
"editor.formatOnType": false,
"editor.formatOnPaste": false,
}
"[cs]": {
"editor.defaultFormatter": null,
"editor.formatOnSave": false,
"editor.formatOnType": false,
"editor.formatOnPaste": false,
},
"[c#]": {
"editor.defaultFormatter": null,
"editor.formatOnSave": false,
"editor.formatOnType": false,
"editor.formatOnPaste": false,
},
"csharp.format.enable": false,
"omnisharp.useEditorFormattingSettings": false,
"razor.format.enable": false,
And yeah, I know [cs] and [c#] are not the correct language IDs, but... pure desperation.
EDIT: Fixes when I manually download v2.90.60 and install that. EDIT 2: This looks like the most recent formatting-related commit. Just in case it's helpful at all.
