The runtime service that’s responsible for making the mapping between IL code and native processor instructions is called the Just-in-Time compiler, often abbreviated as JIT and referred to as “the jitter.”

Note: Restricting Target Execution Platforms

Although IL code is machine-independent, the .NET language compilers provide a /platform switch to request JIT compilation to a particular assembly language. Although the portability across machine architectures is a ...
