Following this guide that adds a custom complex claim Json serialized to an inst

Answer 1

The cast in GetPassport tries to convert from base type Claim to derived type ComplexClaim which will result in null. You need to write a cast operator to convert from Claim to UKPassport

public static explicit operator UKPassport(Claim c)
{
     return (c == null ? null:JsonConvert.DeserializeObject (c.Value));
}       

and GetPassport will be

private static UKPassport GetPassport(this ClaimsIdentity identity, string passportType)
{
   return (UKPassport)identity.Claims.FirstOrDefault(c => c.Type == @"http://it.test/currentpassport");
}
