If you need to distinguish between these two cases (for example, in instrumented caches tracking hit/miss metrics), use the non-generic <see cref="M:Microsoft.Extensions.Caching.Memory.IMemoryCache.TryGetValue(System.Object,System.Object@)" /> method instead, which returns <c>true</c> if the key is present regardless of type.
