Compiler Error C3828

'object type': placement arguments not allowed while creating instances of managed or WinRTclasses

Remarks

When creating an object of a managed type or Windows Runtime type, you cannot use the placement form of operator ref new, gcnew or new.

Example

The following example generates C3828 and shows how to fix it:

// C3828a.cpp
// compile with: /clr
ref struct M {
};

ref struct N {
   static array<char>^ bytes = gcnew array<char>(256);
};

int main() {
   M ^m1 = new (&N::bytes) M();   // C3828
   // The following line fixes the error.
   // M ^m1 = gcnew M();
}
