c# - Disadvantage of making class to Serializable

Question

I'm using Azure Cache preview and need to make some classes Serializable.

Is there any disadvantage of making class to be Serializable - such as performance issue?

[Serializable]
public class MyClass {}

I found few related questions, but they are not about disadvantages.

1. Are all .NET exceptions serializable?

2. Drawbacks of marking a class as Serializable

Thank in advance

Answer 1

No, there is no intrinsic overhead simply in being marked as [Serializable]. The only problem I'd have is that BinaryFormatter and NetDataContractSerializer are lousy serializers, and most other serializers aren't interested in this flag (ok, I may be biased)
