c# - Throw Exception inside a Task - "await" vs Wait()

Question

static async void Main(string[] args)
{
    Task t = new Task(() => { throw new Exception(); });

    try
    {                
        t.Start();
        t.Wait();                
    }
    catch (AggregateException e)
    {
        // When waiting on the task, an AggregateException is thrown.
    }

    try
    {                
        t.Start();
        await t;
    }
    catch (Exception e)
    {
        // When awating on the task, the exception itself is thrown.  
        // in this case a regular Exception.
    }           
}

In TPL, When throwing an exception inside a Task, it's wrapped with an AggregateException.
But the same is not happening when using the await keyword.
What is the explanation for that behavior ?

The goal is to make it look/act like the synchronous version. Jon Skeet does a great job explaining this in his Eduasync series, specifically this post:
