I'm not 100% sure if this is the right call of me, but during my investigation of the memory usage of my solution I saw JsonProperty allocating for each Name call.

I was using this property of JsonProperty some times in a JsonConverter<T> and taking a look at it

I recognized _name is never properly set, so I think it should be removed completely from JsonProperty and maybe add a hint that Name allocates for each call? Also the WriteTo could be cleaned up.

If this is correct I would be happy to contribute a PR for this.
