[Mono-list] replacement for mscoree.dll
Mon, 30 Dec 2002 16:53:23 +0100
I don't know if anyone has worked on this yet, but I did a small
experiment creating a replacement for mscoree.dll.
It's very "rude", but it works for simple applications (just a "proof of
concept"). Maybe someone is interested in working on this in the near
This is how it works (as far as I understand):
When you build a .NET executable you get a PE executable. This consists
out of 2 parts: the.NET code and a small stub (x86 code).
The stub references mscoree.dll and calls a function. For simple
applications it calls _CorExeMain (there are some other function in
there, but this is the one I used).
Now, this _CorExeMain function can locate a decent .NET runtime
(example: Mono) and have it execute the .NET code contained in the PE file.
What I did was very simple: just find out what the commandline (exe
filename) was and call the mono.bat file (from the mono for windows
distribution) with the found exe (as I said, "very rude").
mscorlib, Version=1.0.3300.0, Culture=neutral,
1 file(s) copied.
_CorExeMain> going to execute Mono with [test.exe]
mscorlib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
_CorExeMain> Press Any Key to Exit
Now the next step(s) could be
* directly call the mono jit/interpreter api in order to execute the
.NET code (can this be done?)
* correctly find out the application path (path to .exe) + parameters
passed on the commandline
p.s. I can send the example code if anyone wants (5kb zipfile, VS7 project)
