Need help with record equality comparison

[FLAMESpl]

I have following xUnit tests:

using System;
using Xunit;

namespace RecordEqualityTest;

public record Entity(Guid Id)
{
    public virtual bool Equals(Entity? other) => other?.Id == Id;
}

public record EntityWithCode(Guid Id, string Code) : Entity(Id)
{
    public virtual bool Equals(EntityWithCode? other) => base.Equals(other);
}

public class UnitTest1
{
    private static readonly Guid id = Guid.NewGuid();
    private readonly Entity entity = new(id);
    private readonly EntityWithCode entityWithCode = new(id, "Test");

    [Fact]
    public void Test1() => Assert.True(entity.Equals(entityWithCode));

    [Fact]
    public void Test2() => Assert.True(entityWithCode.Equals(entity));

    [Fact]
    public void Test3() => Assert.True(entity == entityWithCode);

    [Fact]
    public void Test4() => Assert.True(entityWithCode == entity);
}

I would like to have all tests passing, however test 2 and 4 fails. It turns out that when EntityWithCode is left hand argument then Equals method from base class is not called, because parent record has generated member bool Equals(Entity) that hides one from base record, what it does is calling Equals(EntityWithCode) with null argument.

I tried overriding EntityWithCode.Equals(Entity) like EntityWithCode.Equals(EntityWithCode) does but it won't compile with message "member with the same signature is already declared".

How do I make proper equality comparison here?

You don't use a record. See Andy's answer here: #5586 (comment).
