Visual Studio-style folding

[Sensuikan-U511]

Visual Studio recognises the line above a free-standing opening bracket as the basis for folding and folds it all into one line, like so:

In comparison, even with extensions, the closest I can get to replicating this behaviour in VSCode is this:

I have been informed by the extension developer that it is not possible to fix this issue by extension.
Although I've come to prefer VSCode in all other aspects, this lone issue does detract from the experience of using it as someone who has always written code in Allman-style. It doubles the vertical space consumed by a folded block, and it's much less clean to read.
If this will not be accepted as a feature, I would be grateful to receive a pointer as to where I could change this behaviour so that I can build a personal fork.

#3352 captures the request to have closing bracket in the folded region.

There's currently no plan to work on such a feature.

I think my request was misunderstood for a different, commonly-asked request. I was not requesting closing brackets captured in folding region. You are correct that this is already handled by an extension, which I mentioned in my request.

You want the folding marker to be with the function identifier, not on the opening bracket.
That decision is made by the language extension that you use. In your case C#?
e.g. for TypeScript, there the folding marker stays on the identifier.

You could file a request against the C# extension.

That is exactly correct. I cannot replicate the behaviour captured in your GIF. Even if I write a Typescript snippet, the folding marker stays with the opening bracket. I tried disabling extensions as well to make sure nothing I had was interfering with the default behaviour.

Is the behaviour in the GIF the result of a Typescript-specific extension? I notice, also, that in the GIF the opening bracket is hidden when collapsed, while when I attempted to try this without extensions only the lines between the brackets are collapsed.

Thats strange. It's not what I see with TypeScript.
Yes, the language extensions contribute a folding provider that is in full control where the folding ranges start and end.
That said, as a user you can switch to indentation based folding using the setting "editor.foldingStrategy": "indentation".
Maybe that's what you currently use?
