I'm starting a project using EF 4 and POCO.
What is the best practice for sending data to the client ? Should I send the POCO or I should have a DTO instead?
Are there any issue I should be aware of when sending the entity (that is disconnected from the context) to the client ?
Is it a recommended practice to send the POCO to the client layer?
For me, one of the main reasons to use EF4 with POCO is the fact that you don't need DTO's. I can understand using DTO's with traditional EDMX files where your entities are pretty bloated, but this isn't the case.
Your POCO obviously needs to be serializable, but there really shouldn't be any issues specific to sending POCO entities that don't also occur with DTO's.
