Compiler Error C3455

'attribute': none of the attribute constructors matched the arguments

An invalid value was used to declare an attribute. See attribute for more information.

The following sample generates C3455.

// C3455.cpp
// compile with: /clr /c
using namespace System;

[attribute("MyAt")]   // C3455
// try the following line instead
// [attribute(All)]
ref struct MyAttr {
   MyAttr() {}
};
