I would like to cache the n most recent items using Microsoft.Extensions.Caching.Memory. Once the cache size hits n, the oldest item should be evicted to make room for the newest.

I can set the size limit like so:

use memoryCache = new MemoryCache(MemoryCacheOptions(SizeLimit = 10_000L))

But I’m not sure how to configure the eviction.

Can this be done? If so, how?
