In his book, Domain Driven Design (DDD), Eric Evans encourages the use of Value Objects in domain models. Here at Pluralsight we are using the DDD approach to modeling, and we are taking his advice and using immutable objects to implement all of our Value Objects in our domain layer. What we're finding is that we are programming in C# but our code is becoming more and more functional in nature, which has lots of benefits. Less mutable state tends to make things easier to test, and tends to reduce bugs. Sure you can hide an object's state behind public methods and property getters, but if you really want to implement immutable objects, you should consider surfacing the class's internal state via readonly fields. Indeed it becomes as simple as this: public class Cooldown . And that's because objects in C# with readonly fields require that those fields be initialized by a constructor. Net Domain-driven Design With C# SwitchImagine a call to a constructor for an object with several arguments - this can get unreadable very quickly. Ugh. new Cooldown( . Now I can construct a readonly object and not lose any clarity around what each argument means, because I can call the constructor using named arguments. Cooldown( ability: . It's certainly no harder to type, and it's just as easy to read. One gotcha to this approach is that many data binding frameworks will only bind to property getters, ignoring public fields. This isn't a problem for us here at Pluralsight, because our domain model is isolated from tech like this. Data binding frameworks don't come into play until you're up in our application layer, and in that layer we use separate view model classes that do have property getters and setters to play nice with ASP. NET MVC, the Razor view engine, etc. A second gotcha is that there aren't any mainstream serializers or O/R mappers that I know of that know how to rehydrate an immutable object via its constructor. Even Auto. Mapper can't handle this today. Most of this tech relies on calling a default constructor to get an instance of an object, then calling property setters (or setting the values of fields) to rehydrate its state. But once again, this is not a problem at all here at Pluralsight, because our domain objects aren't directly serialized - our persistence layer has a set of data transfer objects that are designed to be serializer friendly. And we explicitly avoid Auto. Mapper in favor of code gen'd mappers which are friendlier to refactoring tools like Re. Sharper. The beauty of all of this isolation is that we are establishing a pristine domain layer devoid of tech, leaving only concise business logic. We've even managed to eliminate the need for Get. Hash. Code until it's absolutely needed!
