Example my "issue" with C#'s naming convention. While most modern language have a "camel case" convention, C# uses an "upper camel case" (or "pascal case") convention. This cause problem when translating from, let say, JavaScript (JSON), or XML into C#.

User.cs

public class User {

  // composed class
  public enum UserRole {
    Guest = 0,
    Subscriber = 1,
    Supervisor = 2,
    Editor = 3,
    Publisher = 4,
    Administrator = 5
  }

  public int Id { get; set }
  public string Login { get; set; }
  // ex: UserRole UserRole.... O_o  ... see below...
  public UserRole UserRole { get; set; }

}

public static class UserManagement {
  
  public static ValidateAdminPrivilege(User user) {
    return user.UserRole == User.UserRole.Administrator;
    //  ^ Instanc.Property
    //                   ^ Class.Enum
    // -> The only difference is the 'u' for the instance...
  }
