Promises: A newer asynchronous technique that uses a promise object to receive the results of an asynchronous operation. You'll see this in newer code bases and in newer Node.js APIs. You might have to write promise-based code in your work to wrap older APIs that won't be updated. By ...
Notice that the SpeakerService is using the Promise.resolve method to return a Promise that is instantly resolved. This is an easy way to mock out the service without having to build a Promise object in the longer fashion using the Promise constructor. Next, the SpeakerDet...
promise from this async activity to delay the completion of the “processed” event until the activity completes. The processed event is called whenever your app navigates to a particular page fragment so make sure any code specific to activation is only run on a navigation that is triggered by...

This video walks you through the experience of authoring and running a workflow to build your application, restore environment to a clean snapshot, deploy the build on your environment, take a post deployment snapshot, and run build verification tests. Version: Visual Studio 2010....
Add a Button control and a TextBox control to your form. Double-click the button to view the implementation of the onClick event of the button in the Code window, and then add the following code: Private Sub Button1_Click(ByVa...
Description: Nobody agrees on how to handle overridden .constructor/.then properties on promise instances. The spec seems to side with V8 based on my interpretation of Await, PromiseResolve, and promise resolve functions, but that breaks...
