Load embedded .net executable directly to memory, which will delete the
calling executable proces filename from disc

I would like to load embedded .net executable directly to memory, which
will delete the calling executable process filename from disc.
I have two executable file A and B 1. File B is embedded into FileA 2.
File A should load it and call its method 3. File A exits. 3. Process from
File B should delete File A and close.
Can method.Invoke be used in such scenerio? I am not so sure if I can load
assembly run and exit leaving it run?
