The fifth edition of David McCarter's book, "Röck Yöur Cöde: Code & App Performance for Microsoft .NET," is now available on Amazon. It offers practical techniques for enhancing .NET application performance, including coding patterns, memory insights, and benchmarking. This definitive guide is essential for modern .NET developers aiming for speed and scalability.
Microsoft advises initializing reference type static fields inline to enhance code readability and prevent issues from uninitialized fields. Two patterns are shown: inline initialization and using a static constructor. While both methods do not allocate memory, using a static constructor may slightly improve performance. EditorConfig can check for adherence to this guideline.
The 20th Anniversary Edition of Rock Your Code: Coding Standards for Microsoft .NET, authored by David McCarter, is now available on Amazon. This comprehensive guide offers updated standards for .NET 10, best practices, and expert insights, making it essential for software engineers aiming for improved code quality and performance over two decades.
In their experience as a software engineer, the author emphasizes the importance of data validation to prevent errors caused by bad input. They introduce Spargine's Validator class, which offers various methods to validate data effectively. Incorporating these methods can lead to cleaner and more reliable code, enhancing application stability.
The article emphasizes the importance of input validation in software engineering, highlighting its role in avoiding errors and maintaining data integrity. It discusses Spargine's Validator class, detailing various validation methods that support seamless integration and best practices for exception handling. The piece advocates for wider implementation of these techniques in .NET development.
String comparisons in .NET are essential for various operations like authentication and sorting, but they must be used correctly to avoid performance issues or bugs. The article outlines the proper use of Equals() for equality checks and Compare() for ordering. It emphasizes measuring performance before assuming Span-based methods are faster, highlighting the importance of intent in choosing string comparison APIs.
In optimizing the Spargine project, I improved performance by avoiding constant arrays as method arguments. Instead, using static readonly fields reduced memory allocations significantly. This change enhanced execution speed, yielding a 1.34x performance gain. I recommend enabling CA1856 warnings in .editorconfig to maintain performance-focused coding practices.
The [ConstantExpected] attribute in .NET enhances code performance by signaling that methods should receive compile-time constants as arguments. While not enforcing this at runtime, it improves coding practices and efficiency. In the Spargine project, it clarified intent and identified issues early, particularly with .NET 10's performance improvements across parameter types.
This content discusses four methods for evaluating items in a collection using predicates or filters, mainly focusing on the LINQ Any() method. It highlights the performance of Count() as superior to Any(), LongCount(), and Exists() under specific conditions, especially in asynchronous operations where CountAsync() is the fastest.
The excerpt discusses the .NET MemoryExtensions class, which optimizes performance in byte array manipulation by offering allocation-free methods for converting to Memory, ReadOnlyMemory, Span, and ReadOnlySpan.
