[Mono-dev] Optimized Dictionary`2

Do you think you could try to update your dictionary implementation so 
that its binary serialization would be compatible with .NET's one? 
Actually, it is not - and so I cannot do remoting or simply file 
exchange with binary-serialized dictionary between a Mono-machine and a 
.NET machine (I would have to use XML/Soap, which is far less 
efficient). To do so, I think there are changes to bring to 
ISerializable only (serialization constructor and GetData method).

Best regards
