Binding tip, only create observable collection once

I thought I’d share a really silly mistake I’ve just made. I have a list selector that is bound to an observable collection in my view model. However, when I was adding items to the collection they were not showing in the list. The mistake I had made was that upon refreshing the list I was using collection = new collection, this breaks the binding. So ensure you only create your target collection and if you want to refresh it then use collection.Clear().

Doh!
