How to use ID property in schema first?

[amoghmc]

I tried using [ID] property in schema first but I keep getting the below error

Unable to resolve type from field 'id'

public class Book
{
    [ID]
    public int Id { get; set; }
    // omitted code
}

builder.Services()
    .AddGraphQLServer()
    .AddDocumentFromFile(...)
    .BindRuntimeType<Query>();

type Book {
    id: ID!
    ...
}

I tried using ID with nameof(Book) and a bunch of other things but it only seems to work with implementation first but not schema first. I want to keep my schema but add the ID attribute to my book for caching.
Any way to do this?
