Why do the results of the Equals and ReferenceEquals methods differ even though variables are reference types?

Question

As per this msdn documentation

If the current instance is a reference type, the Equals(Object) method tests for reference equality, and a call to the Equals(Object) method is equivalent to a call to the ReferenceEquals method.

then why does following code results in two different result of method calls Equals method returning True and ReferenceEquals method returning false, even though the obj and obj1 is reference type as IsClass property returns true.

using System;
                    
public class Program
{
    public static void Main()
    {
        var obj = new { a = 1, b = 1 };
        var obj1 = new { a = 1, b = 1 };
        
        Console.WriteLine("obj.IsClass: " + obj.GetType().IsClass);
        
        Console.WriteLine("object.ReferenceEquals(obj, obj1): " + object.ReferenceEquals(obj, obj1));
        
        Console.WriteLine("obj.Equals(obj1): " + obj.Equals(obj1));
    }
}

Output:

obj.IsClass: True

object.ReferenceEquals(obj, obj1): False

obj.Equals(obj1): True

Answer 1

obj and obj1 refer to 2 different objects, so object.ReferenceEquals() will return false.

Equals() returns true, because the compiler implements Equals() for anonymous types. It will return true if all the properties of both objects have the same values.
