Improved async/await support

I am Semih Okur, a PhD student in the CS department at the University of Illinois. I'm currently doing research on asynchronous programming in phone applications. I developed a tool that automatically improves async/await usages by doing transformations.

The tool found some opportunities in your application. First, it added "ConfigureAwait(false)" to some await statements in order to decrease overhead of capturing the context because the method is not updating UI elements after these statements. Second, it added async call for ReadToEnd and Write method calls in order to improve asynchronous support.
