I'm working on a C# console application that will be responsible for running an array of tasks. The basic structure for that is as follows:
var tasks = workItems.Select(x => Task.Factory.StartNew(() => { DoSomeWork(x); })).ToArray(); Task.WaitAll(tasks); The problem is that DoSomeWork() is an async method which awaits the result of another task, which also needs to await a call to the Facebook API. http://facebooksdk.net/docs/reference/SDK/Facebook.FacebookClient.html#GetTaskAsync(string)
public async void DoSomeWork(WorkItem item) { var results = await GetWorkData(); } public async Task<List<WorkData>> GetWorkData() { var fbClient = new FacebookClient(); var task = fbClient.GetTaskAsync("something"); var fbResults = await task; }; I thought I would be able to support this notion of nested tasks with the call to Task.WaitAll() but the execution of the parent tasks finishes almost immediately. Putting a Console.ReadLine() at the end of the application to prevent it from early execution shows that the result will indeed come back later from Facebook.
Am I missing something obvious or is there a better way to block for my Task collection that will allow for this kind of scenario?
