What is IL?
for Microsoft Intermediate Language. We can call it as Intermediate Language
(IL) or Common Intermediate Language (CIL).
programming language (C#, VB.NET, J# etc.) does not compile into executable
code; instead it compiles into an intermediate code called Microsoft
Intermediate Language (MSIL).
the compile time, the compiler convert the source code into Microsoft
Intermediate Language (MSIL) .MSIL is a CPU-independent set of instructions
that can be efficiently converted to the native code.
MSIL TO JIT:
During the runtime the CLR Just In Time (JIT)
compiler converts the Microsoft Intermediate Language (MSIL) code into native
code to the Operating System. When a compiler produces Microsoft Intermediate
Language (MSIL), it also produces Metadata. The Microsoft Intermediate Language
(MSIL) and Metadata are contained in a portable executable (PE) file .
Intermediate Language (MSIL) includes instructions for loading, storing,
initializing, and calling methods on objects, as well as instructions for
arithmetic and logical operations, control flow, direct memory access,
exception handling, and other operations Just In Time Compiler
computer's processor executes the native code.
