Question

I am using the new async await features to upgrade from backgroundworker in C#. In the following code I am trying to replicate the execution of multiple tasks with ContinueW

When you use Task.Wait(), you are basically saying "wait here my task to complete". That's why you are blocking the thread. A good way to handle exception in tasks is using the Task.ContinueWith overload and pass OnlyOnFaulted as TaskContinuationOption which would look like:

Task yourTask = new Task {...};
yourTask.ContinueWith( t=> { /*handle expected exceptions*/ }, TaskContinuationOptions.OnlyOnFaulted );
