How NativeAOT compiles C# directly into native x64/ARM64 machine code ahead-of-time:

In .csproj:

<PropertyGroup>
  <PublishAot>true</PublishAot>
  <StripSymbols>true</StripSymbols>
  <OptimizationPreference>Speed</OptimizationPreference>
</PropertyGroup>

Key Advantages:

• Instant Startup: Boots in 2 to 4 milliseconds (zero JIT compilation delay at runtime!).
• Tiny Memory Footprint: Base memory usage drops from 35MB down to ~8MB.
• Zero .NET Runtime Dependency: Self-contained executable with no .NET SDK or runtime required on target machine.

NativeAOT is ideal for CLI tools, Lambda microservices, and containerized Kubernetes pods where cold-start latency is paramount.

Just make sure your dependencies avoid runtime reflection and dynamic code generation (Assembly.Load, Reflection.Emit).
