This code can be used to task a async task and run it without the async part.

AsyncHelper.cs

    public static class AsyncHelper
    {
        private static readonly TaskFactory _myTaskFactory = new 
            TaskFactory(CancellationToken.None, 
                TaskCreationOptions.None, 
                TaskContinuationOptions.None, 
                TaskScheduler.Default);

        public static TResult RunSync<TResult>(Func<Task<TResult>> func)
        {
            return AsyncHelper._myTaskFactory
                .StartNew<Task<TResult>>(func)
                .Unwrap<TResult>()
                .GetAwaiter()
                .GetResult();
        }

        public static void RunSync(Func<Task> func)
        {
            AsyncHelper._myTaskFactory
                .StartNew<Task>(func)
                .Unwrap()
                .GetAwaiter()
                .GetResult();
        }
    }
