Add relationships to anime, manga and character

The kitsu website by default does not show nsfw content including the API is there anyway to enable this or login to my account with the wrapper because the attributes for an anime has nsfw value aswell.

Right now the description on characters gives html code you can tidy it up with something like this.

Not really very good at json, but whenever the GetCharacterAsync() method tries to deserialise the json into a CharacterModelByName object it returns an object with id, type and attributes all as null.

I have used NuGet to add Kitsu 1.4.2
If I create a NetCore2.0 console app everything works perfectly
But in .NET 4.7.2 I get this error

System.TypeLoadException
HResult=0x80131522
Message=Could not load type 'Kitsu.Anime.AnimeDataModel' from assembly 'Kitsu, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
Source=Kitsu
 StackTrace:

4.7.2 should be Net Standard 2.0 compatible?

Any idea on why and how to fix this?
