How to move the template cast operator outside the class?

Question

C++ / C#

In general, is it possible?
The code below compiles fine, but I have no idea how to take it out of the class.

class Experimental {

    template<typename Type> operator Type() {
            return Type();
    }

};

Answer 1

class A
{
public:
   template <typename T>
  operator T() const;
};
 
template <typename T>
A::operator  T() const
{   
   return T();
}
