Couldn't insert a record with nullable id

TL;DR: Repository with the tests. More specifically:

• LiteDatabaseInsertTests
• LiteRepositoryInsertTests

Model:

public class Customer
{
    public int? Id { get; set; }
    public string Name { get; set; }
}

Test:

var col = _liteDatabase.GetCollection<Customer>();

var customer = new Customer
{
    Name = "John Doe",
};

col.Insert(customer);

Assert.True(col.Exists(x => x.Id == customer.Id));

Actually col.Insert throws an exception:

LiteDB.LiteException : Invalid BSON data type ‘Null’ on field ‘_id’.

Fails for both LiteDatabase and LiteRepository.

BTW: null and 0 are not the same. Null means it has not been set. 0 means it has been set… to 0.

I would think there’s a strong argument for Auto Increment Id properties to be int? so we know they have not been set.
