问题 I need to bind a property of a control to an attached property in XAML (so that the attached property becomes a source of the binding), and I can't figure out how to do it -- VS2015 gives me " Value does not fall within the expected range " error, and when I run the app, I get an exception.

问题 My big-picture problem: I need to send a signal from a Windows 10 desktop app (or a service, really) to a UWP XAML MVVM app on the same OS instance / machine. I was using named semaphores in the global namespace, but these don't work at all on UWP (by design, for security reasons maybe). No joy. I tried UWP sockets, and this works with the UWP as listener only if the client is on a remote machine. Is this a security design decision, too? No idea. Exempting the app from loopback restriction

问题 I am building a new Windows 10 UWP (Universal Windows Platform) app using Visual Studio 2015.

I load that "paginated" HTML into a second, hidden WebView on the XAML page that I resize to fit exactly one page based on the user
