// This library redirects JavaScript console function calls to also pass their string
// payload along to window.external.notify, so that a UWP application can catch and log
// them to the Visual Studio console. Note that line numbers are lost in this process.
//
// This is useful for Visual Studio 2019 and later, as they lack built-in debugging
// tools for the original WebView control. If you are using Visual Studio 2017, you are
// better off using the built-in Script debugging tools instead.
