I making the twitter client on CSharp and CoreTweet.
And I creating UserPage, I found a issue(Bug?).
A issue is to get Description’s Entities.
On Browser, sucsessfully created UserMentions link.
But UserMentions isn’t containing in ‘User.Entities.Description.UserMentions’.

So, I looked User JSON data on GET users/show - ユーザープロフィールを取得する.
