This is how you use TPL to crash your host process - don't ask me why you would use it in this way....

Program.cs

static void Main(string[] args)
{
    try
    {
        var factory = new TaskFactory();
        var task = factory.StartNew(() => { throw new Exception(); });
        task.Wait();
    }
    catch (Exception ex)
    {
        Console.WriteLine("I have found an exception");
        throw ex;
    }
}

// or to do it even simpler

static void Main(string[] args)
{
    var factory = new TaskFactory();
    var task = factory.StartNew(() => { throw new Exception(); });
    task.Wait();
}
