using namespace System;

[System::ObsoleteAttribute]
ref struct S {
   [System::ObsoleteAttribute]
   int i;

   [System::ObsoleteAttribute]
   void mFunc(){}
};

// Any reference to Func1 should generate a warning
[System::ObsoleteAttribute]
Int32 Func1(Int32 a, Int32 b) {
   return (a + b);
}

// Any reference to Func2 should generate a warning with  message
[System::ObsoleteAttribute("Will be removed in next version")]
Int32 Func2(Int32 a, Int32 b) {
   return (a + b);
}

int main() {
   Int32 MyInt1 = ::Func1(2, 2);
   Int32 MyInt2 = ::Func2(2, 2);

   S^ s = gcnew S();
   s->i = 10;
   s->mFunc();
