Add Callback when a value gets evicted

[Raildex]

In my case, my values are IDisposable and use native resources.

A callback when an item gets removed from the cache is necessary to properly cleanup the resources.

A Action<TValue> as a constructor argument would be great.

Why would you not use KeyValuePair<TKey, TValue> instead of the TKey as the argument for the EvictionCallback?

@GabrielMarquezMatte good question. I don't know😀
Will change in next release
