Shorthand syntax for creating entites #39
Description
It would be very handy to use anonymous objects to create entities, especially ones with a blank id. Currently a blank node id must be explicitely created
var entity = context.Load<IPerson>("some URI");
var blankId = entity.CreateBlankId();
var address = context.Create<IAddress>(blankId);
address.City = "New York";
entity.Address = address;Here's how this could work instead
var entity = context.Load<IPerson>("some URI");
entity.Address = new {
City = "New York"
};Internally a new blank identitifier would be generated for the anonymous object and each property would be translated to the destination type. In this case the properties would have to match those of IAddress.

Additionally it could be possible to declare an
Idproperty. If present it would be used instead of the generated blank node identified.The question is how should the Name property be treated? After all it is possible that an entity already exists for the given Uri. Should the supplied values replace whatever values the already existed.

Lastly the
IEntityContextcould be extended to enable creating new entities in a concise way.Similarly to my previous comment it remains to be decided what should happen if the entity already exists.
