Use the sync API if available, file a bug if it is not available and it is our code :smile: Invoking async APIs synchronously in a good way requires some ceremony, e.g. we have code like this in Identity:
``` C#
    internal 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 _myTaskFactory.StartNew(func).Unwrap().GetAwaiter().GetResult();
        }
 
        public static void RunSync(Func<Task> func)
        {
            _myTaskFactory.StartNew(func).Unwrap().GetAwaiter().GetResult();
        }
    }
```
