C ++ / CLI Dll with the problem of interacting with C #

I have 3 projects in one solution.

I have:

  • native C ++ dll,
  • C # Winform,
  • and a C ++ / CLI proxy without clean mode to perform communication between two other projects (and use the built-in function in managed C # code)

So when I run the application, everything works. But when I click the "Generer" button in my winform, which performs the NativeMethod :: Test () C ++ / CLI function, that it crashes, and I have this pop-up message:

An unhandled exception of type 'System.BadImageFormatException' occurred in System.Windows.Forms.dll

Additional Information: Failed to load file or assembly "EngineInterfaceWrapper.dll" or one of its dependencies. n'est pas une Win32 valide application. (Exception from HRESULT: 0x800700C1)

When I go to projects in Conf. Properties -> Linker -> Advanced: Target Machine, it is set with the value "MachineX86" for my native and managed C ++ DLL, and my WinForm is also in X86. I am tired of many configurations, but this does not work.

Edit:

The problem may be the "TradeEngine.h" header in the C ++ / CLI header: EngineInterfaceWrapper.h. Because when I disconnect my own C ++ Dll (and delete all the code in the CLI shell), if I create a solution it will work, but if "#include" TradeEngine.h "" is always in the CLI header, I will have this same mistake. Do you have an idea?
