Danny Thorpe recently wrote a very nice post on via Databinding Collection Properties in WPF that sometimes fail without warning.
The short summary is that this fails without warning when binding to properties that do not explicitly implement the IList interface, for instance when binding to a collection that supports only IEnumerable (because of yield return) or IList<T> (for instance when binding to a Dictionary<TKey, TValue>.Values, which implements IList<T>, but not IList).
Thanks Danny for blogging about this (he explains it way better than I can), and putting a warning that the workaround Dictionary<TKey, TValue>.Values.ToList() potentially can have a big impact on memory consumption.
Life would be so much easier if WPF could bind to IEnumerable or IList<T> :)
