How to add a feature to the Visual Studio editor?

Question

visual studio

Can this be done at all? I want that when working with the code, the declarations of methods in the class are displayed in bold (for example, in relation to C# code). For example, the editor has this class:

public partial class FieldHelper
{
    public MvcHtmlString In__Value(string name, string value, int maxLength, ControlWidthEnum width, string cssClass, bool autocomplete, object attributes)
    {
        var input = new HtmlInputText(name, value);
        input.MaxLength = maxLength;
        input.CssClass = cssClass;
        input.Autocomplete = autocomplete;
        input.Attributes = attributes;
        return RenderWidth(input.ToString(), width);
    }
}

You want
public MvcHtmlString In__Value(string name, string value, int maxLength, ControlWidthEnum width, string cssClass, bool autocomplete, object attributes)
to be bold and the rest to be standard. Well, to make it visually more convenient to work.
