Microsoft .NET Code Analysis: When CountAsync() Outperforms AnyAsync() in .NET
The article critiques code analysis rule CA1828 in Microsoft .NET, which suggests using AnyAsync() over CountAsync() for checking item existence in IQueryable collections. Benchmark results indicate CountAsync() outperforms both AnyAsync() and LongCountAsync(), pointing to potential inefficiencies in following CA1828. The author recommends adjusting rule severity to optimize performance.
Microsoft .NET Code Analysis: Creating Empty Arrays
Arrays are popular in .NET for their efficiency. The .NET team recommends avoiding zero-length allocations, opting instead for Array.Empty() or using the [] expression for creating empty arrays. The latter is faster than both new string[0] and Array.Empty(), marking a shift in performance standards in recent .NET versions.
Unlock Performance Gains in .NET: The Power of Custom Comparers
This article highlights the importance of custom comparers in .NET for enhancing application performance when sorting and ordering collections. It discusses the flexibility and control that custom comparers offer over default comparers and provides examples of creating them. Benchmarks also illustrate the performance benefits, while cautioning that custom comparers may introduce overhead in certain scenarios.

Microsoft .NET Code Analysis: Leveraging Span-Based String Concatenation for Improved Performance
String concatenation in .NET can be optimized by using the Span type to enhance performance and reduce memory usage. By replacing traditional methods with AsSpan() and string.Concat(), memory allocations decrease significantly, yielding substantial performance gains. Adhering to best practices helps identify and rectify inefficient concatenation patterns.
