Cache Builders

Builders are provided for both ConcurrentLru and ConcurrentLfu to make it easy to configure cache options.

For example, this is how to create a ConcurrentLru with scoped values, and GetOrAdd that is both async and has atomic value creation:

IScopedAsyncCache<int, Disposable> lru = new ConcurrentLruBuilder<int, Disposable>()
   .WithAtomicGetOrAdd()
   .AsScopedCache()
   .AsAsyncCache()
   .WithCapacity(3)
   .Build();
