The post discusses optimizing array iteration in programming by caching the array's length for performance improvements. This method yields a 1.021x performance boost, particularly beneficial for loops executed frequently. The author encourages this technique and recommends their book for more insights on enhancing .NET code performance.
This article discusses the importance of hash codes in programming and optimization techniques in Microsoft .NET. It explores different methods for generating hash codes, with RuntimeHelpers.GetHashCode() identified as the fastest option. The article concludes by introducing a new extension method, FastGetHashCode(), for faster hash code generation in projects.
The content emphasizes the importance of storing user-visible strings in project resources for globalization. It introduces the CompositeFormat class from .NET 5, highlighting its benefits: consistent formatting, ease of maintenance, enhanced readability, flexible options, localization support, parameter reusability, and separation of logic from presentation. Notably, it offers performance advantages over other formatting methods.
.NET version 8 introduced the FrozenSet type, offering immutable and hashable set collection with benefits including improved performance, memory efficiency, and thread safety. Benchmarks show comparable performance to List, outperforming HashSet and ImmutableHashSet. However, it is slightly slower than the latter in lookups. FrozenSet offers significant advantages for concurrent applications and memory optimization.
The FrozenDictionary is a thread-safe, immutable, read-only dictionary optimized for fast lookups. It outperforms the Dictionary, reducing iteration and lookup times significantly.
On June 10th, 2024 at 9 AM PST, I'll be appearing on "On.NET Live" for the second time. We'll delve into code performance in .NET 8 through the Code Performance Game. Join the live show for an engaging session. For more details, visit https://youtu.be/4WX14dsnKsg.
The article demonstrates the ease of serializing and deserializing collections using JsonSerializer.
Using ContainsKey() followed by an indexer on dictionaries results in a double lookup, decreasing performance. This is common anti-pattern. This article will show you how to fix this and increase performance up to 2x.
The article explores four methods for examining items in a collection using predicates, with a focus on performance. A Twitter poll revealed that over 50% of developers favored the LINQ Any() method, prompting the author to verify its efficiency in comparison to other options like Count() and Exists().
The article advocates for initializing reference type static fields inline to enhance code readability and prevent unexpected behavior caused by uninitialized static fields. Microsoft recommends initializing these fields at the point of declaration to improve clarity. The article provides examples demonstrating the issue and the recommended solution, emphasizing the use of static constructors for initialization.
