| JIT is the process of compiling MSIL code units just when needed at runtime. The JIT compiler in the Common Language Runtime (CLR) compiles MSIL instructions to native machine code as a .NET application is being executed. Compilation occurs when a method is called and is not compiled more than once during program execution; because, JIT-compiled code is cached in memory.
