At some point in the code (heavy load) the AesManaged class is being used, are there any performance gains from this implementation compared to RijndaelManaged, and should there be any risk when changing from AesManaged to RijndaelManaged concerning heavy load? g...
I have a scenario where I will have to kick off a ton of threads (possibly up to a 100), then wait for them to finish, then perform a task (on yet another thread).

In .NET (at least <=2) there's a problem serializing objects that raise events when those events are handled by a non-serializable object (like a Windows Form). Because of the way VB.NET implements events, when you serialize an object, its events get serialized too (because events are actually implemented using hidden multicast delegate...
