c++ cli - Entry point for C++/CLI x64 WindowsForms App (VS 2015)

Question

I have the same problem as the user in Visual Studio 2015 c++/CLI boost::thread : If I use boost, Windows Forms and C++/Cli together, my app crashes on startup.

The proposed solution works for me (change Subsystem to Console); the only small disadvantage is that the console is started alongside the GUI.

There is another solution I've found (see https://bytes.com/topic/net/answers/642179-c-cli-winforms-app-native-static-library-singletons-cra) : Changing the entry point to "?mainCRTStartupStrArray@@$$FYMHP$01AP$AAVString@System@@@Z".

However this only works when compiling for 32 bit; for 64 bit the symbol cannot be resolved. My questions:

• Is there a similar symbol that works for x64 as well?
• How could one find these kind of symbols? I tried to locate them via dumpbin but with no success!

Ah, light at the end of the tunnel for this nasty ignored problem. You can find the correct mangled name by grepping the .lib files in vc/lib/amd64. Out pops msvcmrt.lib, the name is:

?mainCRTStartupStrArray@@$$FYMHP$01EAPE$AAVString@System@@@Z

Bit of a bug in the mangling algorithm btw, it shouldn't have added the extra E's because these are managed identifiers. Links and runs fine, I haven't tested yet if it solves the static initialization order fiasco problem. It is promising.
