AutoWeakIndexerTKey, TValue Class

A thread safe, DictionaryTKey, TValue like implementation that populates it's content on demand, i.e. calling indexer[key] will never return null. The cache has only weak references to the values, so the values may come and go.

Public Extension MethodFindIndexKeyValuePairTKey, TValue Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the entire IEnumerableT.
(Defined by CollectionExtensions)
Public Extension MethodForEachKeyValuePairTKey, TValue Performs the specified action on each element of the collection.
(Defined by CollectionExtensions)
Public Extension MethodForEachKeyValuePairTKey, TValue Performs the specified action on each element of the collection, providing also the index of the item.

Remarks
This implementation is thread safe; the draw back is that generating new items is slow, so this type is not suitable for caching a large amount of items.
