'class' : a member using-declaration or access declaration is illegal within a managed type

A using declaration is invalid within all forms of managed classes.

The following sample generates C3182.

// C3182a.cpp
// compile with: /clr /c
ref struct B {
   void mf(int) {
   }
};

ref struct D : B {
   using B::mf;   // C3182, delete to resolve
   void mf(char) {
   }
};

The following sample generates C3182.

// C3182b.cpp
// compile with: /clr:oldSyntax
#using <mscorlib.dll>

__gc struct B {
   void mf(int)
   {
   }
};

__gc struct D : B {
   using B::mf;   // C3182, delete to resolve
   void mf(char)
   {
   }
};

int main()
{
}
