C# Native AOT: Compiling .NET Apps to Native Machine Code for Maximum Performance
Speed of C, Productivity of C#: The Rise of Native AOT in .NET For decades, the execution model of .NET has relied on two phases: compiling C# source code into Intermediate Language (IL) , and then using a Just-In-Time (JIT) compiler at runtime to convert that IL into machine instructions for the host CPU. While this JIT compilation model allows for amazing runtime optimizations, it comes with unavoidable costs: slower startup times (JIT compilation overhead) and a larger memory footprint. With the release of .NET 8 and maturing rapidly in .NET 9 and .NET 10, Microsoft has brought **Native AOT (Ahead-of-Time)** compilation to the forefront. Native AOT compiles C# code directly into architecture-specific machine code at build time. The JIT compiler is completely bypassed, and the result is a lean, self-contained, lightning-fast native binary. ⚡ The Power of Native AOT Why should modern software engineers care about Native AOT? The benefits are game-changing for cloud-native a...
