Intermediate Language (IL)

.NET languages are not compiled to machine code. They are compiled to an Intermediate Language (IL).

CLR accepts the IL code and recompiles it to machine code. The recompilation is just-in-time (JIT) meaning it is done as soon as a function or subroutine is called.

The JIT code stays in memory for subsequent calls. In cases where there is not enough memory it is discarded thus making JIT process interpretive.
