Applying Domain-Driven Design and Patterns: With Examples in C# and .NET Jimmy Nilsson
Publisher: Addison-Wesley Professional

Having finished it earlier this week I wanted to do some justice to . For those trying Businesses have processes and tasks they do, and DDD attempts to bridge the gap between developer and domain expert by applying patterns that help transfer a model of reality into code. With this said, Domain-Driven Design (DDD) is no exception. Books on design patterns catalog a vast array of patterns, many focused around interfaces, but often seem overwhelming to those developers who are making their first foray into software design. Introductory texts on C# provide the basic syntax and a few simple examples, but do not have enough detail and depth to help the reader understand how powerful interfaces are, and where they should best be used. Azure, C#, .NET, Architecture & Related Tech News I'm a big fan of the Domain-Driven Design (DDD) principles and patterns so pre-ordered Vaughn Vernon's “Implementing Domain-Driven Design” prior to it's release in March this year (2013) . Techniques like If you Google “repository pattern” or look for NHibernate examples, you'll find plenty of resources on how to apply the technical patterns. A more implementation related approach focusing on the mechanics of the implementation of tactical DDD with C# and .Net. Value object pattern explicitly allows you to replace a leg in an itinerary without fearing that you'll unknowingly change the itinerary of a completely unrelated cargo. NET mailing list, the DDD mailing list, and any other medium where DDD comes up. Covering both Application services and Domain services, providing solid definitions and ample architectural and code examples. As it turns out, researching this topic wasn't easy. NET objects clean, although the database model gets a bit dirty. Applying Domain-Driven Design and Patterns (Addison Wesley). This is yet another area I knew enough about to be dangerous but I certainly was no expert. The pattern To keep this practical, I'll use a classic cargo example from the blue book – cargo is an entity here, itinerary and legs are value objects. Domain-driven design (DDD) is an approach to the design of software, based on two premises. Value objects are one of the basic building blocks of object domain driven design.
