I don't know exactly what you are doing here, but there is a gotcha with deserialization (at least binary deserialization. I don't know, but I suspect that it is the same for XML serialization). On deserializing a List or a Dictionary, the list is filled with null values (or default value if it is a value type) until the deserialization constructor has been exited. Only after exiting the constructor is the list filled with the actual, deserialized Ts.

This means that if you want to do something with the list, it cannot be done in the constructor. You can instead make a method which contains any work which needs to be done with the list, and as long as it is annotated with the [OnDeserializedAttribute] attribute, it will be called after the list has been filled but before the deserialization returns. The method can have any name.

See MSDN for details.
