Library doesn't really work for refresh tokens

[sherlock1982]

When I call AcquireTokenByAuthorizationCode with ConfidentialClientApplication I got a refresh token.

It doesn't have any expiration info and therefore DistributedCacheEntryOptions parameters comes with all nulls.
The code in GetOptions puts there default sliding expiration time of 20 minutes.

This is wrong because this token generally should be treated as never expired.

Can you provide more context? I can't see any relation between OAuth token and this library, I am not sure I understand the issue
