The C# code compilation process involves several steps, including preprocessing, compiling, linking, loading, and execution. It validates the source code for errors and generates an executable program.
The C# compiler preprocesses the source code by expanding any macros and performing conditional compilation.
During this step, the C# compiler transforms the C# code into an intermediate language (IL).
During this step, the intermediate language (IL) code is combined with any required resources (such as external assemblies or resources) to create an executable or a library.
The compiled code has been loaded into memory and is ready for the common language runtime to execute (CLR).
The common language runtime (CLR) manages the execution of the compiled code, providing services such as garbage collection and exception handling.
