Custom naming rules defined in .editorconfig do not work

[arkaragian]

I want to define a rule where I can define C style #define naming rules. For example the following examples are acceptable by my style

const string HELLO_WORLD = "Hello World!";
const string HELLO = "Hello World!";

But with my default .editorconfig setup I get the following diagnostic:

Diagnostics:
Remove the underscores from member name pmtk.Models.prline.HELLO_WORLD [CA1707]

Thus I have defined a new editorconfig rule:

# Custom Naming Style for const string values to mimic C style #define formatting
dotnet_naming_style.c_style_define.capitalization = all_upper
dotnet_naming_style.c_style_define.required_prefix =
dotnet_naming_style.c_style_define.required_suffix =
dotnet_naming_style.c_style_define.word_separator = _

# Symbol specification for const string fields
dotnet_naming_symbols.const_string_fields.applicable_kinds = field
dotnet_naming_symbols.const_string_fields.applicable_accessibilities = public, private, protected, internal
dotnet_naming_symbols.const_string_fields.required_modifiers = const

# Naming rule for const string fields to follow C style #define formatting
dotnet_naming_rule.const_strings_c_style.severity = error
dotnet_naming_rule.const_strings_c_style.symbols = const_string_fields
dotnet_naming_rule.const_strings_c_style.style = c_style_define

But this does not seem to work.
