System.MissingMethodException (Cannot create an instance of an interface) when trying to deserialize data #7

Closed MagicAndre1981 closed 5 years ago

MagicAndre1981 commented 5 years ago

While playing with preview 5 to validate my issue I get JSON that is somehow not recognized by VS2017 and when I try to deserialize the JSON I provided in issue 6 (var empList = JsonGo.Deserialize.Deserializer.SingleIntance.Deserialize<List<EMPLOYEE>>(value);), I get an System.MissingMethodException with error message Cannot create an instance of an interface :

Hi, Please check Preview6

new version generates NullreferenceException:

In the same .cs file where you changed this, maybe also check for null for all other usage of Deserialize.
