NettetCaching. Simple, fast, effective FIFO and LRU Cache with events and persistence. This Caching library provides a simple implementation of a FIFO cache (first-in-first-out) and an LRU (least-recently-used) cache. It is written in C# and is designed to be thread-safe. Usage. Add reference to the Caching DLL and include the Caching namespace: NettetWe use two data structures to implement an LRU Cache. Queue is implemented using a doubly-linked list. The maximum size of the queue will be equal to the total number of frames available (cache size). The most recently used pages will be near the front end and the least recently used pages will be near the rear end.
