I like my object initializers to look like this:
new Point { Label = g.Key.Name, Claims = g };
When hit the semicolon key, they get reformatted like this:
new Point {Label = g.Key.Name, Claims = g};
Where is the option to stop my padding from being removed?
If you are using an .editorconfig file, you can control this behaviour by adding:
space_within_single_line_array_initializer_braces = true
See also the official resharper documentation on supported .editorconfig entries. These typically let you customize everything you could customize from the formatting styles menu for all of Jetbrains' IDEs.
