                High-performance systems and algorithms (reasons for C# & .NET)
              
          
    Great question — C# has grown a lot in the last decade, and there are several features in the language and ecosystem that make it very capable for building high-performance systems while still being relatively high-level compared to C or Rust. Let’s break it down by categories of features relevant to algorithms, data flows, and concurrency:

🔹 Memory & Data Structures

struct and readonly struct


Value types allocated on the stack (or inline in arrays/fields).
Avoid GC overhead compared to reference types.
