serialization

Based on my understanding SerializableAttribute provides no compile time checks, as its all done at runtime, then why is it required for classes to be marked as serializable?

Couldn't sterilizer just try to serialize an object and just fail? isn't it what it does right-now when something is marked, it tries and fails. wouldn't it be better if you had to mark things as unserializable rather than serializable? that way you wouldn't have the problem of libraries not marking things as serializable?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
