The common language runtime provides the infrastructure that enables managed
execution to take place as well as a variety of services that can be used during 
execution. Before a method can be executed, it must be compiled to processor-specific 
code. Each method for which Microsoft intermediate language (MSIL) has been 
generated is JIT-compiled when it is called for the first time, then executed. The next 
time the method is executed, the existing JIT-compiled native code is executed. 
The process of JIT compiling and then executing the code is repeated until execution 
is complete. During execution, managed code receives services such as automatic 
memory management, security, interoperability with unmanaged code, cross-language 
debugging support, and enhanced deployment and versioning support.

Excerpt from the book "Analects":

『１』子曰：「學而時習之，不亦說乎？有朋自遠方來，不亦樂乎？人不知而不慍，不亦君子乎？」  
『２』有子曰：「其為人也孝弟，而好犯上者，鮮矣；不好犯上，而好作亂者，未之有也。君子務本，本立而道生。孝弟也者，其為仁之本與！」  
『３』子曰：「巧言令色，鮮矣仁！」
