test

using System;
using System.Threading.Tasks;

namespace TestException
{
    class Program
    {
        static void Main(string[] args)
        {
            var p = new Program();
            p.AsyncMain().Wait();
            Console.ReadKey();
        }

        public async Task Run()
        {
            try
            {
                await SomeJob2();
            }
            catch (Exception e)
            {
                Console.WriteLine($"{e.GetType()}");
            }
        }

        public async Task SomeJob()
        {
            throw new Exception();
        }

        public Task SomeJob2()
        {
            try
            {
                return SomeJob();
            }
            catch (Exception e)
            {
                throw new AggregateException(e);
            }
        }

        public async Task AsyncMain()
        {
            await Run();
        }
    }
}

So, output will be 'exception'. If we wait for async task in SomeJob2 it will be 'aggregateexception'
