Optimize .NET type design by sealing classes, using readonly structs, and preferring static pure functions to reduce memory allocations and improve execution speed. This approach minimizes overhead and enhances JIT optimization.

Use a readonly struct instead of a class in C# when you need value type semantics and want to avoid heap allocations. Readonly structs prevent defensive copies, improving execution speed and reducing memory overhead.

The best way to handle collections in high-throughput C# APIs is deferring enumeration and choosing appropriate collection types. This minimizes premature materialization, reducing memory allocations and improving overall throughput.

Sealing classes improves .NET performance by enabling the JIT compiler to apply more aggressive optimizations, such as devirtualizing method calls. This reduces dispatch overhead and increases execution speed.

Yes, you can use Span<T> and Memory<T> for efficient byte manipulation in .NET. These types provide safe, managed access to contiguous memory regions without allocating new arrays on the heap.

Use ValueTask instead of Task in C# when your async method often completes synchronously. This avoids allocating a Task object, reducing memory overhead and improving performance in high-throughput scenarios.
