Error when parsing a nested object initialization

[YeskaNova]

1. Description

Hi,

We can't use the lambda expression parser to create a lambda expression that has nested objects ( which may be useful for EF core to update for example a referenced entity ):

Expression => new (new (3 as Id) as CurrentDepartment)

2. Example code which has error

using System;
using System.Collections.Generic;
using System.Linq;
using System.Data.Entity;
using System.Linq.Dynamic.Core;
					
public class Program
{	
	public static void Main()
	{
		var srcType = typeof(Customer);
		var lambda2 = DynamicExpressionParser.ParseLambda(ParsingConfig.DefaultEFCore21, srcType, srcType, "new (new (3 as Id) as CurrentDepartment)");
	}
		 
	
	public class Customer
    {
        public int Id { get; set; }
        public Department CurrentDepartment { get; set; }
    }
	public class Department
    {
        public int Id { get; set; }
    }
}

3. Exception

If you are seeing an exception, include the full exception details (message and stack trace).

Unhandled exception. System.NotSupportedException: Unable to promote expression 'new Customer() {Id = 3}'.
