Why does my C++/WinRT project get errors of the form ‘winrt::impl::produce‘: cannot instantiate abstract class, missing method GetBindingConnector

Why does my C++/WinRT project get errors of the form “consume_Something: function that returns ‘auto’ cannot be used before it is defined”?

Why does my C++/WinRT project get errors of the form “unresolved external symbol … consume_Something”?
