Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

Please add a code sample. I tried with the folloing sample and it worked
foo.ts

//#region
Test
//#endregion
//#region
Test2
//#endregion

• ctrl + k / ctrl + 8: folds all regions
• ctrl + k / ctrl + 9: unfolds all regions

@aeschli sorry, i should have specified the language.

It looks, it's ok for .ts file.

But for .cs file, it doesn't work.

public class foo
{
    #region newregion
    int i = 0;
    #endregion
}

Do you use an extension for c# ?

Out of the box you get indentation based folding with region markers sand your example works the same way as my example.
But maybe an extension adds language specific folding and doesn't mark the regions correctly.

Yes, i use c# extension that powered by omnisharp. My whole extension list;
