System.runtime.compilerservices.unsafe Version 4.0.4.1 〈2027〉

1. Introduction System.Runtime.CompilerServices.Unsafe is a foundational .NET library that provides a set of low-level, opt-in APIs for direct memory manipulation . Version 4.0.4.1 is a specific, stable release within the .NET Core 2.0 / .NET Standard 2.0 era, though it remains backward compatible with many modern runtimes (up to .NET 8+).

For application developers, this library remains an —you rarely need to call it directly. For library authors building performance-critical components, Unsafe is an indispensable tool, and version 4.0.4.1 remains a reliable choice for compatibility with .NET Standard 2.0 ecosystems. // Bypass bounds checking – DANGEROUS ref T
