Answer 1

you can't use native vectors in managed code.

 

You can write a wrapper DLL in C++/CLI to copy data from the native heap to the managed heap (gcnew+pin_ptr+memcpy). If you prefer streaming your data you can implement a COM interface like IStream (declared in Windows SDK's Objidl.h) and refer to it as System::Runtime::InteropServices::ComTypes::IStream from managed code.
