Serialization of Dictionary<> and Thread Synch

[Jon Guest]

Hi

I may be being stupid here (as I haven't tried it yet) but if I have WCF
Service which returns a static Dictionary<K,V> object (which I understand is
serializable in WCF) and another thread were to modify that collection while
it were serializing, what would happen?

Does the framework take care of it (e.g. snapshot the collection), or would
I need to synchronize the addition/removal of Dictionary objects with the
service that returns the Dictionary to calling clients?



Thanks

In such cases I don't take a chance and copy object ( Dictionary in your
case ) under Sync object ( Lock()/Monitor()... )
before return copied object from service, so I'm calm that object will be
returned to client without changes

If the serialization process use an enumerator on the dictionnary while it
serialize... The dictionnary.add method will crash, doesn't it ?
