I've done a lot of research when creating my unmanaged resource

I am 100% sure that there are only two temporary files used by csc.exe:

First one is a .res format file in the directory of the assembly that
contains the default resources (version info and optionally icon). (Only
when no /win32res is specified because it overrides default resource.)

The second one in %TEMP% is an .obj format file as Zac said but it is
created by cvtres.exe (I don't know why they use cvtres.exe instead of
integrating it to their PE generator) that isn't linked at all, it is
however interpreted by the PE generator and is written to the PE file
directly without using a linker or advanced object file interpretation as
the PE file generator assumes that it is the output of cvtres.exe.
