Working with Promises in Windows Store Apps

To deal with the complexity involved in asynchronous programming, Windows Store apps make use of what is known as a Promise. The implementation of Promises in Windows Store apps is based on Common JS Promises proposal. At code level a promise is an object that represents the result of an asynchronous operation and returns a value at some later time in the future. Promises make it easy to work with asynchronous operations in Windows Store apps. This article discusses what promises are and also shows how to use them in a Windows Store app.
