How to add items to AutoSuggestBox() programatically

[vflich]

Hello, I'm facing with AutoSuggestBox(), but I can't reach append items to it programatically in C++. I tried the next:

winrt::Windows::Foundation::Collections::IVector<hstring> l = single_threaded_vector<hstring>();
l.Append(hstring(L"Opcion1"));
l.Append(hstring(L"Opcion2"));
e.ItemsSource(l);

e is the AutoSuggestBox control. My code compile but crash in runtime in the e.ItemSource(l), with an exception.

How is the correct way to insert text options in an AutoSuggestBox control programatically?

Thanks!
