Dynamic.InvokeMember throws RuntimeBinderException on async method

[fmichellonet]

Hi,

I'm working with Azure.Data.Tables nuget package and while i'm trying to call an async method on an internal class a RuntimeBinderException is thrown.
Here is a test that highlights this error.

using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
using Azure.Data.Tables.Models;
using Dynamitey;
using NUnit.Framework;

namespace Azure.Data.Tables.WithDynamitey.Tests
{
    public class WhereAsyncShould
    {
[Test]
        public async Task Failing()
        {
            string tableName = "WhereAsyncShould";
            var serviceClient = new TableServiceClient("UseDevelopmentStorage=true");
            var client = serviceClient.GetTableClient(tableName);
            var restClient = Dynamic.InvokeGet(client, "_tableOperations");


            var response = await Dynamic.InvokeMember(restClient, new InvokeMemberName("QueryEntitiesAsync", false), new object[]
            {
                new InvokeArg("table", tableName),
                new InvokeArg("timeout", (int?)10),
                new InvokeArg("queryOptions", BuildQueryOptions(client)),
                new InvokeArg("cancellationToken", CancellationToken.None)
            });

            Assert.That(response, Is.Not.Null);
        }

        private static dynamic BuildQueryOptions(TableClient tableClient)
        {
            var t = typeof(TableItem).Assembly.GetType("Azure.Data.Tables.Models.QueryOptions");
            var opts = Dynamic.InvokeConstructor(t);
            Dynamic.InvokeSet(opts, "Format", Dynamic.InvokeGetChain(tableClient, "_defaultQueryOptions.Format"));
            return opts;
        }
}

Any help would be appreciated.
