SourceProvider asynchronous sources

[Mark]

        public override IList GetSource(string sourceName)

        {

            var list = new List<LookupValue>();

            if (!string.IsNullOrEmpty(countryCode))

            {

                var task = CurrentState.Instance.ServiceClient.ListAllProvinces(countryCode);

                var items = task.GetAwaiter().GetResult();

                list.AddRange(items);

            }

            return list;

        }

I want to call an async method from my GetSource provider...is there a documented approach to achieve this? The above code locks and causes the app to stall.
