    Migrating away from Rust.

    The development of Architect of Ruin initially began in Rust with the Bevy game engine due to personal preferences and the positive community around Bevy. However, challenges such as collaboration difficulties, abstraction issues, rapid iteration needs, migration pain, and modding limitations prompted a switch to Unity and C#. The team conducted an experiment evaluating core features implementation, leading to a full port decision. The switch resulted in faster development, better collaboration, and improved maintainability.

    Why C#?

    C#, a programming language developed by Microsoft, is known for its modern, multi-paradigm capabilities and has continuously evolved to include features like object-oriented programming, generics, lambdas, LINQ, and async/await. It benefits from a robust .NET ecosystem, excellent tooling like Visual Studio, and a vast library collection via NuGet. C# is suitable for developing cross-platform applications across web, mobile, desktop, and cloud environments, supported by extensive documentation and a vibrant community.

    🎨 Abstract Factory Pattern in C# 14

    The Abstract Factory Pattern allows developers to create families of related objects without specifying their concrete classes, which is valuable in applications supporting multiple themes, platforms, or environments. This pattern helps maintain decoupled, scalable, and maintainable code. Using C# 14, you'll have better architectural clarity and ease in implementing variations like light and dark UI themes. The pattern aligns well with enterprise software requirements and plays nicely with Dependency Injection frameworks.

    The "in" keyword in C# is Awesome

    The 'in' keyword in C# allows structs to be passed by reference while making them read-only within the method for performance optimization. This avoids costly copying of large structs. However, if the struct isn't marked as readonly, hidden defensive copies may occur, reducing performance benefits. Combining 'in' with 'readonly struct' or read-only members maximizes performance gains.

    The New Extension Members of C# are INSANE

    Nick introduces a new feature in .NET called extension members, which allows developers to add instance and static members to types using the new 'extension' keyword. This feature enhances existing extension methods by enabling extension properties and extending functionality without being limited to static methods. Nick demonstrates how to implement and use these new features through various examples and discusses the potential impact on how developers write C# code.

    Don't use async void in C#

    Async void methods in C# should generally be avoided because they can't be properly awaited, leading to issues with error handling and control flow. The only appropriate use of async void is in event handlers, where tasks are not returned.

    The LINQ trap in .NET

    Understanding the deferred execution in LINQ is crucial as it can cause unexpected data changes in .NET. LINQ methods like where, select, and take build a query rather than executing immediately. This allows adding conditions dynamically, but beware of data changes before execution, as they will reflect in the results. Knowing these rules makes LINQ a powerful tool.

    How to use guard clauses in C#

    Guard clauses in C# help improve code readability and maintainability by eliminating unnecessary nested constructs and branches. They are used to validate conditions or input parameters, stopping the execution of methods early if criteria are not met. This practice prevents runtime exceptions and ensures valid data processing. The post provides practical code examples and highlights the advantages of using guard clauses over traditional validation methods.
