Hi, the environment is the next:

1. SQLServer (connectionUrl="sqlserver://MYSERVER/DO40-Tests")
2. Session with a DisconnectedState.
3. Entity with a DateTime field, datetime (not nullable)

It creates a new entity, the data are saved and retrieved by a query. It throws the following error: {"Version of entity with key 'MyEntity, (1)' differs from the expected one."}

MyEntity myentity = new MyEntity();` // datetime = 01/01/0001 (DateTime default in DO)

sessio.SaveChanges();

var t1 = sessio.Query.All<myentity>().First();` // {"Version of entity with key 'MyEntity, (1)' differs from the expected one."}
(datetime in the SQLServer is 01/01/1753, DateTime default in SQLServer)

Perhaps everything is correct, but is this the desired behavior?

Thanks,

PD Obviously, when DateTime is nullabe all is OK.
