FSharp Entry Types with Entity Framework-First Database

Question

I am doing a proof of concept in a line of a business application where I want to change the current implementation of the C # Code-First Entity Framework using F # one. I am following this article, which seems to work very well, but I was hoping to use FSharp record types instead of the classes that the article uses. When I try to add data annotation to a record type, for example:

type Family = {[<Key>]Id:int; LastName:string; IsRegistered:bool}

I get the following error:

Error   1   The type 'Key' is not defined

Is there a way to use data annotations with record types? EF Code-First seems to require annotation ...

Answer 1

Record types support attributes just fine (and with your syntax).
