Okay, I see it is a duplicate of https://github.com/Azure/aspnet-redis-providers/issues/190

But how can I tell which class is not set as serializable that causes this exception?

This is what I get from my custom RedisLogger implementation:

Okay, I see it is a duplicate of #190

But how can I tell which class is not set as serializable that causes this exception?

This was addressed in PR #193

I will leave this issue open until a new version is released
