I’m using async/await and Task a lot but have never been using Task.Yield() and to be honest even with all the explanations I do not understand why I would need this method. Can somebody give a good example where Yield() is required? 5 Answers 5
Is there any difference between: const [result1, result2] = await Promise.all([task1(), task2()]); and const t1 = task1(); const t2 = task2(); const result1 = await t1; const result2 = await t2; and const [t1, t2] = [task1(), task2()]; const [result1, result2] = [await t1, await t2]; 5 Answers 5
At the moment, I’m attempting to use async/await within a class constructor function. This is so that I can get a custom e-mail tag for an Electron project I’m working on. customElements.define(‘e-mail’, class extends HTMLElement { async constructor() { super() let uid = this.getAttribute(‘data-uid’) let message = await grabUID(uid) const shadowRoot = this.attachShadow({mode: ‘open’}) shadowRoot.innerHTML … Read more

I need to run multiple async tasks in a console application, and wait for them all to complete before further processing. There’s many articles out there, but I seem to get more confused the more I read. I’ve read and understand the basic principles of the Task library, but I’m clearly missing a link somewhere. … Read more
Edit: This question looks like it might be the same problem, but has no responses… Edit: In test case 5 the task appears to be stuck in WaitingForActivation state. I’ve encountered some odd behaviour using the System.Net.Http.HttpClient in .NET 4.5 – where “awaiting” the result of a call to (e.g.) httpClient.GetAsync(…) will never return. This … Read more
I’m trying to understand async await in the simplest form. I want to create a very simple method that adds two numbers for the sake of this example, granted, it’s no processing time at all, it’s just a matter of formulating an example here.
