Private / Protected / Internal changes

using System;
using TypeKitchen;

namespace test2
{
    public class SimpleType
    {
        internal string ThisIsAString { get; set; }
    }

    internal class Program
    {
        private static void Main()
        {
            var instance = new SimpleType();

            try
            {
                var accessor = WriteAccessor.Create(typeof(SimpleType), AccessorMemberScope.All, out _);
                accessor[instance, "ThisIsAString"] = "test";
            }
            catch (Exception ex)
            {
                Console.Write("error occured : " + ex.Message); // error occured : Attempt by method 'Write_SimpleType_Fields\, Properties_Private_D80BA31E4EC25FD8C444170139A6190E.set_Item(System.Object, System.String, System.Object)' to access method 'test2.SimpleType.set_ThisIsAString(System.String)' failed. 
            }


            if (Environment.UserInteractive)
                Console.ReadKey();
        }
    }
}

i'm trying to access an internal property but without success... Is that an expected behavior ? I'm not sure to understand the goal of AccessorMemberScope.All if it can't actually access anything else than public.

@erwan-joly It should be able to -- let me see if I can reproduce your issue.

The late-binding accessor wrapper isn't kicking in when it should. There also seems to be an issue in the IL for callvirt. I'll get a patch out hopefully this weekend.

i tried fixing this by myself but without success. FYI : it doesn't work for both field and properties. The exception in case of Field is System.FieldAccessException : Attempt by method 'Read_FooStructPrivate_Fields\, Properties_All_D903032FFB3253D3D893C6C0F3799B0.get_Item(System.Object, System.String)' to access field 'TypeKitchen.Tests.ReadAccessorTests+FooStructPrivate._foo' failed.

from my understanding it field doesn't use callvirt but Ldfld so i'm not sure of what is happening there :/

Hi all!

I'm able to set up internal or private members via private members accessor WriteAccessor.Create(obj, AccessorMemberTypes.Properties, AccessorMemberScope.Private, out members) but behavior is misleading. For instance instead of 228911010879111168 accessor writes value 1330348548968.
