Instead of compiling the entire application at once, the JIT compiler simply compiles each portion of code as it is called just in time. When code has been compiled once, the resultant native executable is stored until the application exists so that it does not need to be recompiled the next time that portion of the code is run.
This process is more efficient than compiling the entire application code at the start. This shows that the execution of the MSIL code will be almost as fast as executing native machine code. The use of MSIL facilitates language interoperability. One can compile to MSIL from one language, and this compiled code should then be interoperable with code that has been compiled to MSIL from another language. In other words, MSIL architecture enables the framework to be language neutral.
To a large degree, language choice is no longer dictated by the preference of the developer or the team. One can even mix languages in a single application.
A class and an exception are thrown in a C method that can be caught in a VB method. Things like buffer overflows and unsafe casts can be caught at compile-time, greatly reducing maintenance headaches.

It means write your code once in any language C , F , VB or any other and it can run on different environment. It is like bytecode in JAVA. Though it is platform independent it is not executable. NET Framework, or. CLR is in charge of taking the managed code, compiling it into machine code and then executing it.
On top of that, runtime provides several important services such as automatic memory management, security boundaries, type safety etc. In the unmanaged world, the programmer is in charge of pretty much everything. The actual program is, essentially, a binary that the operating system OS loads into memory and starts. Everything else, from memory management to security considerations are a burden of the programmer. Managed code is written in one of the high-level languages that can be run on top of.
When you compile code written in those languages with their respective compiler, you don't get machine code. You get Intermediate Language code which the runtime then compiles and executes.
