Bug: CollectionViewSource crash in PublishAoT mode when using IEnumerable

[dotMorten]

Description

Binding this with PublishAoT causes a runtime crash:

    {
        get
        {
            var groups = (from item in Samples
                         orderby item.Category
                         group item by item.Category into g
                         select new SampleGroup(g) { Key = g.Key ?? "Misc" });
            return groups; // If you add .ToList() here no crash
        }
    }
    CollectionViewSource m_CollectionViewSource;
    public CollectionViewSource CollectionViewSource
    {
        get
        {
            if(m_CollectionViewSource == null)
            {
                m_CollectionViewSource = new CollectionViewSource()
                {
                    IsSourceGrouped = true,
                    Source = SamplesByCategory,
                    ItemsPath = new PropertyPath("Items")
                };
            }
            return m_CollectionViewSource;
        }
    }
}

Steps To Reproduce

1. Run the attached project: App17.zip
2. Observe the crash:
   
3. Remove PublishAoT=true and sample runs
4. Add ToList() to the SamplesByCategory return value, and problem goes away

Expected Behavior

No crash ;-)

This is a known issue, as LINQ uses internal enumerable types, which cannot be detected by the CsWinRT AOT optimizer.

Revisiting this I can't even assign a List<string> or string[] to the ItemsSource property of a ListView without getting the (unhelpful) System.ArgumentException: 'Value does not fall within the expected range.' error.
