sorry about late answer, had some important test during last few weeks.
Hmmm... actually i never made this project to an end. Without going into details it needed such a tremendous amout of work to make it work properly.
Beside, dll injection as more advantages, in particular :
- better optimization (eg. link time code generation)
- allow debugging from visual studio
- use of any library
- more control over what's actually done
- use of c++ cli

And im pretty sure there should be a way to merge a dll with an exe really easily. (Maybe with the restriction of using static libraries), so its not unlikely i make a tool like this someday.

Since visual studio doesnt support multi-process debugging i made a library to allow it. Tell me if u need it. (This way u make a dll, then for debugging u specify an exe that inject the dll then start wow, then ur wow and the dll is being debugged through VS)

I guess u already though about it but what about using blizzard updater to redistribute ur modules? Then u just need a small modification of the client to make it auto inject those modules.
