Handling Complexity: Introducing Complex Value Objects in .NET

While simple value objects wrap single primitives, many domain concepts involve multiple related properties (e.g., a date range’s start and end). This article introduces Complex Value Objects in .NET, which group these properties into a cohesive unit. This ensures internal consistency, centralizes validation, and encapsulates behavior. Discover how to implement these for clearer, safer code using the library Thinktecture.Runtime.Extensions, which minimizes boilerplate when handling such related data.

Smart Enums: Beyond Traditional Enumerations in .NET

Traditional C# enums often fall short when needing to associate data or behavior with constants, or ensure strong type safety. This article explores the “Smart Enum” pattern as a superior alternative. Leveraging the library Thinktecture.Runtime.Extensions and Roslyn Source Generators, developers can easily implement Smart Enums. These provide a robust, flexible, and type-safe way to represent fixed sets of related options, encapsulating both data and behavior directly within the Smart Enum. This results in more maintainable, expressive, and resilient C# code, overcoming the limitations of basic enums.

Value Objects: Solving Primitive Obsession in .NET

Overusing primitive types like string or int for domain concepts (“primitive obsession”) causes bugs from missed validation, like invalid emails or negative monetary values. This article explores Value Objects as a .NET solution. Learn how these self-validating, immutable types prevent entire classes of errors, make code more expressive, and reduce developer overhead. We’ll demonstrate creating robust domain models with minimal boilerplate, improving code quality without necessarily adopting full Domain-Driven Design, and see how Roslyn Source Generators make this practical.

Data Access in .NET Native AOT with Sessions

.NET 8 brings Native AOT to ASP.NET Core, but many frameworks and libraries rely on unbound reflection internally and thus cannot support this scenario yet. This is true for ORMs, too: EF Core and Dapper will only bring full support for Native AOT in later releases. In this post, we will implement a database access layer with Sessions using the Humble Object pattern to get a similar developer experience. We will use Npgsql as a plain ADO.NET provider targeting PostgreSQL.

Native AOT with ASP.NET Core – Overview

Originally introduced in .NET 7, Native AOT can be used with ASP.NET Core in the upcoming .NET 8 release. In this post, we look at the benefits and drawbacks from a general perspective and perform measurements to quantify the improvements on different platforms.

Background Jobs with Rx.NET

As a backend developer you have to implement some kind of periodically running background jobs from time to time. Most widely used tools I see are timers, tasks, semaphores, half dozens of booleans and enums to keep the state. Depending on the complexity of the code, understanding it can be quite adventurous. Alas, almost none of the developers I asked about reactive extensions (Rx.NET) know that they even exist.
