Asked On January 28, 2019 06:08 PM UTC

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.
