serialization of dictionary

Question

I have lists of objects that I want to store in the session and I'm declaring them like this:

Dictionary<DateTime, List<MyObjects>> SessionMyObjects = new Dictionary<DateTime, List<MyObjects>>();

I'm reading some posts that suggest that dictionaries are not serializable and storing dictionaries in the session will cause errors. What is this about? I'm using InProc; there's no serialization with this storage type? If the code compiles, could I still get some strange errors later because of using this structure?

You should avoid using session unless absolutely necessary. – StingyJack Jan 31 '11 at 18:39 — StingyJack, Jan 31 '11 at 18:39

If I'm using InProc session states, do I need to be concerned about serialization? – frenchie Jan 31 '11 at 18:31
InProc (in process) Session State does not Serialize the Session to persist it, where you will fail is when you or another developer changes the Session state in the config file. – Lloyd Jan 31 '11 at 18:53
