Best practices for serialization of DDD aggregates
According to DDD domain logic should not be polluted with technical concerns like serialization, object-relational mapping, etc.

Should serialization and deserialization be the responsibility of the class being serialized?
I'm currently in the (re)design phase of several model classes of a C# .NET application. (Model as in M of MVC). The model classes already have plenty of well-designed data, behaviors, and interrelationships. I am rewriting the model from Python…

Should serialization and deserialization be "atomic" transactions?
I am wondering if serialization and deserialization of classes should always be treated as an "atomic transaction?"
What I mean is, if an error were to occur during the process of serializing or deserializing a member of an object, should the whole…

What happens if we serialize and deserialize two objects which references to each other?
To make it more clear, this is a quick example:
class A implements Serializable { public B b; }
class B implements Serializable { public A a; }
A a = new A();
B b = new B();
a.b = b;
b.a = a;
So what happens if we serialize a and b objects into a…

Are we queueing and serializing properly?
We process messages through a variety of services (one message will touch probably 9 services before it's done, each doing a specific IO-related function). Right now we have a combination of the worst-case (XML data contract serialization) and…

Does Serialization preclude the use of Dependency Injection?
Simple question: I understand that Serialization in C# requires default constructors. This would eliminate the possibility of using Constructor injected DI (which is generally the favored style of DI, in my reading[citation needed]). So is it really…

How do you fix the wrong-case-sensitivity dictionary setting bug-pattern?
There is a coding anti-pattern I've noticed (while using .Net). You declare a data class, which is supposed to have a dictionary field (or get/set Property), and lets call it 'Properties', for the sake of example. It has a string key type.

Compatibility of Enum Vs. string constants
I was recently told that using Enum:
public enum TaskEndState { Error, Completed, Running }
may have compatibility/serialization issues, and thus sometimes it's better to use const string:
