The Role of Common Intermediate Language
.NET language compilers do not emit native platform code. Rather, they emit platform-independent
instructions called the Common Intermediate Language (CIL). Unlike Java bytecode, CIL is not interpreted. It
is just-in-time compiled (JITed) at runtime. You may see CIL referred to by a few other names: IL or MSIL.
CIL is just-in-time compiled (JITed) to the target platform at runtime. A block of code (method) is JITed when
it is first called by a client. The JITed version of the code is cached for subsequent use. Alternately, you can
use the ngen.exe utility to pre-JIT an entire assembly. Surprisingly, pre-JITing does not always mean better
performance. UI intensive applications seem to benefit the most from pre-JITing.
