If both copy and move constructors are provided, overload resolution selects the move constructor if the argument is an rvalue (either a prvalue such as a nameless temporary or an xvalue such as the result of std::move), and selects the copy constructor if the argument is an lvalue (...

SUMMARYC# builds on the syntax and semantics of C++, allowing C programmers to take advantage of .NET and the common language runtime. While the transition from C++ to C# should be a smooth one, there are a few things to watch out for including changes to new, structs, constructors, and...
Of interest is the fact that the traits such as std::is_copy_constructible used to be called std::has_copy_constructor, but were renamed to put the emphasis on expressions rather than intrinsic properties: something like std::is_copy_constructible<int>::value && std::is_move_assignable<int...
