Yeah, records don't really work with EF Their properties don't have setters, only initializers

You indeed can make record mutable by overwriting with { get; set; } , however @TeBeCo , can you explain what does request keyword does?

Oh. I got scared in the moment, scraping web to see what it does, thinking it is some new feature in preview 😅 ~~non-nullable~~ > non-default 🙂

Address address = new () { Foo = null };

public record Address
{
    public required string? Foo { get; set; }
}

Address address = new () { Foo = null };

public record Address
{
    public required string? Foo { get; set; }
}

This is valid

hi thx for the answer @TeBeCo, i still have the same problem even changing adress into a class, maybe im doing something wrong with the executedupdate setters?
