For an isolated class you could do a read-only workaround by adding a "get" method to your DbContext that does a SqlQuery<> and maps the table to the class internally (the old-fashioned way).

I've worked up a minimal test-case here: https://github.com/timabell/ef-complex-pk

e.g.

public class TestDbContext : DbContext
{

    public IEnumerable GetUberWidgets()
    {
        return Database.SqlQuery("select WidgetId, Name from Widgets")
            .Select(dto => new UberWidget
            {
                UberWidgetId = new IdWrap { IdWrapId = dto.WidgetId },
                Name = dto.Name
            });
    }
}
