When using a projection to get only certain fields from an entity via a LINQ query, allow setting read-only properties such as CreatedOn and FullName (on the Contact entity).

For example, the below query will not build because CreatedOn currently allows only get. I propose adding a setter for it as well.

   var q = from p in ctx.CreateQuery<Account>()
    orderby p.Name
    select new Account
    {
        Id = p.AccountId,
        AccountId = p.AccountId,
        Name = p.Name,
        CreatedOn = p.CreatedOn
    }
