|---------|------------|----------------|
| Activator.CreateInstance | Full support | Full support |
| ActivatorUtilities (DI helpers) | ❌ Not available | ✅ Available (Microsoft.Extensions.DependencyInjection) |
| CreateInstance with Span<T> | ❌ | ✅ |
| Performance improvements | Baseline | Faster (better reflection caching) |
