Undocumented Serialization error

[Sek]

Hi Folks,

While deserialization in C#, i came across this error:

"No assembly ID for object type <MyClassName>".

The error is very abstract. Pls find below the stack trace.

Sek,

I don't know that this is an error. If you could post your code.

Also, do you have the assembly with the type you are trying to
deserialize loaded in the app domain that is deserializing the instance?
