Using value object as as identifier with RavenDB .NET client

I'm looking for an example of how to use a custom class as an identifier with RavenDB .NET client. I have something like this:

class Product
{
    public ProductId Id { get; }

    public Product()
    {
        Id = new ProductId(Guid.NewGuid());
    }
    // ...
}

where ProductId looks like this:

class ProductId
{
    public Guid Value { get; }
    
    public ProductId(Guid value)
    {
        // validation
        Value = value
    }
}

I haven't found any information on that topic in the documentation. Does anyone know to do that?

A document identifier (document ID) is always a string that is associated with the document.
See: https://ravendb.net/docs/article-page/5.0/csharp/server/kb/document-identifier-generation

You can have the server generate the Guid for you:.
See: https://ravendb.net/docs/article-page/5.0/csharp/server/kb/document-identifier-generation#guid
To do that you assign: Id = string.Empty
See: https://ravendb.net/docs/article-page/5.0/csharp/client-api/document-identifiers/working-with-document-identifiers#autogenerated-ids

Else, maybe:

  1. Refactor the current Id property to:
    public ProductId MyId { get; } and init with
    MyId = new ProductId(Guid.NewGuid());

  2. Add another property on the Product class
    public string Id { get; set; }

  3. Use OnBeforeStore to assign:
    Id = MyId.Value
