HybridCache serialization issues when in-memory

[BrianVallelunga]

Description

I'm not sure if this is a bug or a misunderstanding, but when storing only locally, why is the data being serialized? I'd assume I could store any sort of object (interfaces, classes, etc) in a local, memory cache.

Reproduction Steps

My factory function returns a Task of an interface (IBloomFilter in this case). I'm passing the HybridCacheEntryFlags.DisableDistributedCache flag into the cache method as follows:

return hybridCache.GetOrCreate("BloomFilter", factory, HybridCacheEntryFlags.DisableDistributedCache)

Expected behavior

The object wouldn't go through serialization when caching locally in memory.

Actual behavior

An exception is thrown: System.NotSupportedException: Deserialization of interface or abstract types is not supported. Type 'BloomFilter.IBloomFilter'
