How Does C# Code Execute?

C# code executes by first being compiled into Common Intermediate Language (CIL) or Intermediate Language (IL) during the build process. When a C# application is run, the Common Language Runtime (CLR) takes over and just-in-time (JIT) compiles the CIL into native machine code specific to the computer's architecture. This machine code is then executed directly by the computer's processor, allowing the C# application to run and perform its intended tasks.

Execution by Computer's Processor

In this representation:

1. C# source code is compiled by the C# compiler into Common Intermediate Language (CIL) or Intermediate Language (IL).
2. The Common Language Runtime (CLR) takes the CIL/IL code and performs just-in-time (JIT) compilation to convert it into native machine code.
3. The native machine code is executed directly by the computer's processor, allowing the C# application to run.
