   Java vs C# in 2025 - Which One Would I Choose?

   The author prefers C# over Java due to its versatility. C# is seen as more flexible, especially in game development with Unity, web development using ASP.NET Core, and desktop applications on Windows. Java is strong in enterprise-level server-side applications but lacks the same level of versatility as C#, particularly in modern development scenarios. The author encourages developers to be language agnostic and choose the best tool for the task at hand.

   Comparing Records, Structs, and Classes in C#: When to Use What?

   C# offers three main type declarations: classes, structs, and records. Classes are reference types that support object-oriented principles and are ideal for complex data objects. Structs are value types meant for simple, lightweight data structures with no inheritance, making them efficient for value-based comparisons. Records, introduced in C# 9.0, combine features of both classes and structs; they are immutable reference types and provide concise syntax for type declarations. Each type serves distinct scenarios and optimizes specific use-cases.

   Event Sourcing for .NET Developers: From Zero to Implementation

   Event sourcing is a design pattern where changes in a domain are stored as immutable events in an append-only log. By focusing on events instead of state, event sourcing allows the reconstruction of current state through replaying events. Key concepts include events, streams, and projections. The tutorial covers implementing an event-sourced bank account aggregate in .NET, detailing event creation, application, and replaying events to achieve current state.
