NEW POST: Cannot build Perseus

Hi everyone.
I've downloaded both 1.0 and 1.1 versions and I can't buid any of them.
Studio cannot find extension method GetEntityKey in this row:

EntityKey targetKey = context.GetEntityKey(fullEntitySetName, target);

there exists method with such name but it has different parameters list & interface it applies to. I could not find any method that would have such a signature.

Did anyone succeeded in using Perseus?

NEW POST: Change reference on one to one object?

martintr — Tue, 12 Feb 2008 03:45:29 GMT

HI Danny
Sorry to be a pest but I am trying to change references and nothing I try succeeds.
I can use SetEntityKey(null) to set the existing key to null before trying to assign another one
but it seems to not like the context of reattaching a new key.

Any help would be greatfully accepted at this point as it is gettng frustrating.

Thanks

NEW POST: Use of entitybag in real application?

martintr — Sun, 10 Feb 2008 21:20:38 GMT

Hi Danny
I am interested in using Perseus in a real application using WCF Services and Entity Framework.
Would this be a realistic path to follow as I have not yet seen a reliable way to do updates of disconnected Entities using Entity Framework.

Is EntityBag likely to become the standard for doing this sort of work?

I really like what you have done with this application and will likely take it further for my own use.
Would be interested in any comments you may feel to pass on.

Thanks
Martin

Perseus is a small project designed to explore ways for exchanging graphs of Entity Framework entities over WCF web services. The key piece of the project is EntityBag<T> which stores a graph of entities along with change tracking information. Here's hoping no one will use this to store & transport something as nasty as Medusa's head. ;-)
