I get the Compiler Error C2071 when I try to implement the explicit operator bool:

class C
{
public:

    explicit operator bool() const

Answer 1

If you look at a list of features in Visual Studio 2010 you can see that it was not an available feature. A look at What's New for Visual C++ in Visual Studio 2012 shows that is has not been added.
