When you double click on a .net .exe assembly:

• Windows' PE loader kicks in
• If you're on a Windows >= Windows XP it will detect that the executable is a managed executable and will forward it to .net by calling _CoreExeMain in mscoree.dll (_CoreDllMain if you double clicked on a managed .dll). It can use the assembly configuration file to know which runtime to use.
• If you're on Windows < Windows XP, the .exe file contains a small native piece of code that will jump to mscoree.dll's _CoreExeMain or _CoreDllMain.
• Then mscoree.dll initializes the .net runtime, depending on the global configuration, the assembly configuration file, and what not.
• Then if it's a .exe, it will JIT compile its entry point method, and start executing it.
