If you want to respond to the SuggestionsRequested event asynchronously, you must obtain a SearchSuggestionsRequestDeferral object before you edit the suggestion list. Here's an example that shows how.

        public async static void SearchBox_SuggestionsRequested(
            SearchBox sender, 
            SearchBoxSuggestionsRequestedEventArgs args)

            // This object lets us edit the SearchSuggestionCollection asynchronously. 
            var deferral = args.Request.GetDeferral();

            try { 

                // Retrieve the system-supplied suggestions.
                var suggestions = args.Request.SearchSuggestionCollection;
                var groups = await SampleDataSource.GetGroupsAsync();
                foreach (var group in groups)
                    var matchingItems = group.Items.Where(
                        item => item.Title.StartsWith(
                            args.QueryText, StringComparison.CurrentCultureIgnoreCase));

                    foreach (var item in matchingItems)
                foreach (string alternative in args.LinguisticDetails.QueryTextAlternatives)
                    if (alternative.StartsWith(
                        args.QueryText, StringComparison.CurrentCultureIgnoreCase))
            finally {
