Is there a way in Entity Framework to use some complex type as key for an entity and map to existing database?
Let say I have database like this:
create table people ( id int, name nvarchar(128) )
and I'd like to map the following C# class structure to this table:
class PersonId
{
public int Id { get; set; }
}
class Person
{
public PersonId Id { get; set; }
public string Name { get; set; }
}
How could I do that?

What's the point of having a separate PersonId
class if you only have on property? that seems like bad practice to me.
Perhaps all you need is a composite key. To use in in EF you can declare your class like this:
[Key, Column(Order = 0)]
public int column1 { get; set; }
[Key, Column(Order = 1)]
public int column2 { get; set; }
