While basic value objects solve primitive obsession, complex domain requirements need sophisticated modeling techniques. This article explores advanced patterns using Thinktecture.Runtime.Extensions to tackle real-world scenarios: open-ended dates for employment contracts, composite file identifiers across storage systems, recurring anniversaries without year components, and geographical jurisdictions using discriminated unions.

Domain models often involve concepts that exist in multiple distinct states or variations. Traditional approaches using enums and nullable properties can lead to invalid states and scattered logic. This article explores how discriminated unions provide a structured, type-safe way to model domain variants in .NET, aligning perfectly with Domain-Driven Design principles while enforcing invariants at the type level.

Learn how to seamlessly integrate Smart Enums with essential .NET frameworks and libraries. This article covers practical solutions for JSON serialization, ASP.NET Core model binding for both Minimal APIs and MVC controllers, and Entity Framework Core persistence using value converters. Discover how Thinktecture.Runtime.Extensions provides dedicated packages to eliminate integration friction and maintain type safety across your application stack.

Value objects are fundamental building blocks in Domain-Driven Design, serving far more than simple data wrappers. This article explores their strategic importance in bridging technical code and business concepts, enforcing domain rules, and fostering clearer communication with domain experts. Learn how to build robust aggregates, cultivate ubiquitous language, and encapsulate domain-specific behavior using Thinktecture.Runtime.Extensions in .NET applications.
