This week we have learned a lot of C#, XAML, and how to create apps for a Windows 8.1 phone. We have a task of creating a voice-activated calculator, which has taken up all week. Of course, Monday was Memorial Day, so some of us were not in the lab then. I have not completed my app yet; I am having a few issues with getting Cortana to understand voice dictation and make the calculation, but eventually I will figure it out.
