    C# is cool again and you can't avoid it anymore...

    C# has evolved significantly from its enterprise-focused origins into a modern, cross-platform language with features like records, pattern matching, nullable reference types, and async/await. The .NET ecosystem has been transformed with .NET Core (now simply .NET), offering cross-platform support, modular architecture, and excellent performance. Modern C# includes minimal APIs for quick web development, LINQ for database querying, source generators for compile-time code generation, and frameworks like Blazor for frontend development and MAUI for cross-platform mobile apps.

    Golang vs C#: Backend Battle - What Top Companies Choose

    Go and C# represent different philosophies for backend development. Go offers superior memory efficiency (25MB vs 162MB), faster initial response times, and simpler deployment with 6MB container images. C# provides a mature ecosystem, comprehensive tooling, and better enterprise integration. Go excels in microservices and cloud-native applications, while C# dominates desktop applications and enterprise systems. Performance differences narrow under sustained load, with both languages suitable for production workloads. The choice depends on team expertise, infrastructure, and specific project requirements rather than absolute performance metrics.

    7 Underrated C# 12 and C# 13 Features Every Developer Should Know!

    C# 12 and C# 13 introduce several underrated features that significantly improve code quality and performance. Key highlights include collection expressions for cleaner syntax, inline arrays for memory optimization, ref readonly parameters for efficient struct handling, type aliases for complex generics, typed exceptions for better error handling, params span for allocation-free variadic functions, and warning wave 7 for code quality improvements. These features enhance developer productivity while preparing codebases for C# 14's upcoming capabilities.

    Unit of Work Pattern in .NET — Why You Need It and How to Implement It

    The Unit of Work pattern manages database transactions by tracking changes across multiple entities and ensuring they're committed together or not at all. This design pattern provides data consistency, abstracts transaction management from business logic, improves efficiency through batching, and enhances testability. The implementation involves creating repository interfaces, implementing them with Entity Framework Core, defining a Unit of Work interface, and coordinating multiple repositories within a single transaction boundary.

    Browse the .NET code base with the .NET Source Browser

    The .NET Source Browser allows developers to explore Microsoft's .NET source code implementation directly. You can search for specific features like Channel.CreateBounded to understand how they're implemented internally. The browser provides search functionality and links to GitHub repositories, making it easy to learn from Microsoft's own codebase and implementation patterns.

    Are Your LINQ Queries Slowing Down Your App? Here’s How to Fix Them

    LINQ queries can significantly slow down .NET applications through common performance traps like multiple enumerations, deferred execution issues, premature ToList() calls, and fetching unnecessary data. Key optimization strategies include filtering before materializing data, using Select() for projection, caching results when reused multiple times, preferring Any() over Count() > 0, and understanding when queries execute to avoid hidden database hits.

    Domain-Driven Design Principles: Value Objects in ASP.NET Core

    Value objects are immutable entities in domain-driven design that lack identity and are recognized by their values rather than unique identifiers. The article demonstrates implementing value objects in ASP.NET Core through a practical Address example, covering the creation of a base ValueObject class with equality comparison methods, proper Entity Framework Core configuration for non-entity objects, and the benefits of using value objects for domain expressiveness, immutability, and separation of concerns in software architecture.
