The type initializer for 'NetJSONCachedSerializer`1' threw an exception.

I am using NetJSON 1.2.6 in a .NET Core 2.1 console application.

I get the below error when executing this - var json = NetJSON.NetJSON.Serialize(_items);

+$exception {System.TypeInitializationException: The type initializer for 'NetJSONCachedSerializer`1' threw an exception. ---> System.TypeLoadException: Access is denied: 'NetJSON.NetJSONSerializer`1[System.Collections.Generic.List`1[MyApplication.Person]]'.

Hi, could you provide the class structure you are trying to serialize?

Thanks,

I am testing multiple serializers, my model has had no problem with Jil, MessagePack, MsgPack.Cli, Newtonsoft.Json, protobuf-net, Utf8Json.

This is a simplification, but close enough.

public partial class Person
{
    public int PersonId { get; set; }
    public string Firstname { get; set; }
    public string Lastname { get; set; }
    public DateTime DateOfBirth { get; set; }
    public byte[] HashValue { get; set; }    
}

This is a simple model indeed. Using it with .net framework works fine. I would look into the reason why it is showing access denied exception. It should not do that.

I fixed it and pushed the changes to 1.2.7 nuget package. Please test and let me know if you find any other issues.

Thanks,
