System.Text.Json.JsonNamingPolicy Deafult

[VassilAtanasov]

Developers need to be able to use it pass through PascalCase

    public abstract partial class JsonNamingPolicy
    {
        protected JsonNamingPolicy() { }
        public static System.Text.Json.JsonNamingPolicy CamelCase { get { throw null; } }
        public static System.Text.Json.JsonNamingPolicy SnakeCase { get { throw null; } }
/// <summary>
/// Property names are not changed
/// </summary>
public static System.Text.Json.JsonNamingPolicy Deafult{ get { throw null; } }
