.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.
This content discusses exception handling in Microsoft .NET, focusing on application layer and reusable assemblies. It offers insights on preventing exceptions and notifying calling code, and references a related book. The principles are noted to be applicable to other programming languages.
The article demonstrates the ease of serializing and deserializing collections using JsonSerializer.
The upcoming episode on C# Corner TV, show #104, will feature Steve Stedman, CEO of Stedman Solutions LLC. The interview will focus on "Getting to retirement in tech."
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().
I hope you'll join me on Saturday, June 1st, 2024, at 10:00 AM PST on C# Corner TV for show #103! My very special guest for the second time will be Jim Wilcox, Principal Software Consultant and Architect with EQengineered.
Attributes in .NET provide crucial metadata that enhances code clarity, tooling support, and developer experience. They enforce contracts, improve static analysis, and facilitate safe coding practices. By thoughtfully utilizing attributes like [DisallowNull], [DebuggerDisplay], and [DefaultValue], developers can create expressive, maintainable, and user-friendly APIs that benefit both current and future projects.
