Collection of CustomType (Serialization)

I was able to setup a CustomType for serialization but I've got some fairly lengthy nested classes to send when an item is initialized and at the very least, a collection of customtype would be handy. The Serialization Documentation indicated that for Array "T-type can be any of the types listed in this table except byte." ... which surely rules out custom types. ..but for Dictionary "K-type can be any of the types listed in this table." with no limit spec'd on Object. I figured I'd give it a shot.

It didn't work for me. I got two different dictionary related exceptions depending on whether the key was a string or int/byte

I thought I would ask if I did something wrong or if this is not supported.


Exceptions:
