How to add the "Windows.Web.Http" to your project?

I am in the process of changing my Windows 8.1 store application to use TLS 1.2. This was required by the client who recently moved all Web APIs to HTTPS and forced the entire traffic network to use TLS 1.2.

After some research, I saw that the System.Net.Http classes I used for the communication (HttpClient and HttpClientHandler) are not going to help me. I need to use similar API from Windows.Web.H...Read more

So I'm a newbie in this topic, so please forgive me if I ask something obvious.My problem is the resolution of the target machine (DELL Latitude E7440 with touch screen) is 1920x1080, but when I run the app, it runs in 1370x771.

In this case I make use of the "Title" and "Album Artist" properties. This is unfortunately not the case.If I rename any of my custom .ATEF file to .MP3, the meta information are read and shown properly as I ...Read more
