JIT (Just InTime) Compiler in .Net                                In this blog, I’m explaining about JIT Compiler in .Net

JIT stands for Just in time compiler. It converts  the MSIL  code to native code as it is needed  during 

code  execution. It is  called just in time since it converts the MSIL  code to CPU  native  code. When it is

required within code execution.

Different Types  of JIT

1)Pre-JIT: Compiles the entire source code during compilation and is used at the time of deployment.

2) Econo-JIT:Compiles methods that are called during run time.

3)Normal-JIT This complies only those methods that are called at runtime. These methods are       compiled only first time when they are called, and then they are stored in memory cache. This memorycache is commonly called as JITTED. When the same methods are called again, the complied code from cache is used for execution.
