CLR(Common Language Runtime) Common language runtime
FCL(.Net Framework Class Library) .Net Framework class library
2,CLR Structure
CLS: Common language specification (Common Language Specification), Get all kinds of languages into a unified syntax .
CTS: General type system (Common Type System), Convert data types in various languages into unified types
JIT: Just in time compiler (Just In-Time) It is used to compile the converted language into binary language , hand CPU perform .
3,.NET Running mechanism process
All kinds of languages （C#,F#,J# And other corresponding source programs ）——> after CLS,CTS First compilation ——> Unified specification language （ Interlingua ）MSIL(.exe,.dll)——>JIT Second compilation ——> Binary language ——> Running on the CPU in

contrast JAVA Operation mechanism of ：
JAVA——> compile ——> Bytecode file （.class）——>JVM explain （jvm virtual machine ）——> Binary language ——> Running on the CPU in
