C# async event handler vs. normal event handler?

private async void ToolStripPlay_Click(object sender, EventArgs e)
    var task = Task.Run(() => this.Play()).ConfigureAwait(continueOnCapturedContext: false);
    await task;

Open in new window

as opposed to
private void ToolStripPlay_Click(object sender, EventArgs e)

Open in new window

What is the advantage of assigning Play() to a Task and then waiting for that Task to complete, as opposed to just running the task?

I see the Task will run on it's own thread, instead of the UI thread, but it looks like the UI thread waits for the Task to complete before returning. (Play() sets the state to Play mode and returns.)

I don't see any real difference once the event handler is called.  Both block the UI thread until the task is completed.

If play() method is a long running process and by suspending main thread, we should see a potential difference by letting the UI paint events happen.
Chris StanyonWebDevCommented:
When you call await, your program returns to the calling method and so can continue to run (freeing up the UI). It will pick up where it left off once the task has finished. By not calling await, you program will halt at the play call and not return to the calling method until it's finished, therefore blocking the UI.
