[GoogleCodeExporter]

What steps will reproduce the problem?

I have program that have server and n-amount of clients.

1.Serializing and deserailizing concurrent dictionarys and linked lists goes OK 
on Window OS. (Windows 7 server and Windows 7 client)

2. Running same code on Ubuntu Linux server and Windows 7 client (Using Mono on 
server and windows 7 on client) concurrent dictionarys and linked lists goes on 
null state. (Only  goes null.. No exception are thrown)

(Server serializes and client deserializes data)

What is the expected output? 
Expected : Concurrent dictionarys and linked lists that is not null and have 
many items.

I see see instead:
All concurrent dictionarys and linked lists goes null. (Strings and integers on 
classes serializes OK!)

What version of the product are you using? On what operating system?
R668 Mono

Windows 7 as client.
Ubuntu Linux as server.

Please provide any additional information below.

1) On Linux server I had run only apt-get mono... no additional installs.
