Hi,
ok change the CpuType.
For cpu see https://github.com/kyle-github/libplctag/wiki/Tag-String-Attributes

Hi Frank
I still have the issue I tried the csharp-wrapper and it works

internal Tag(Controller controller, string name, int size, int length = 1)
        {
            Controller = controller;
            Name = name;
            Size = size;
            Length = length;
            ValueManager = new TagValueManager(this);
            TypeValue = typeof(TType);

            var url = $"protocol=ab_eip&gateway={controller.IPAddress}";
            if (!string.IsNullOrEmpty(controller.Path)) { url += $"&path={controller.Path}"; }
            url += $"&cpu={controller.CPUType}&elem_size={Size}&elem_count={Length}&name={Name}";
            if (controller.DebugLevel > 0) { url += $"&debug={controller.DebugLevel}"; }

            //create reference
            **Handle = NativeLibrary.plc_tag_create(url, controller.Timeout);**

            Value = TagHelper.CreateObject<TType>(Length);
        }

in line //create reference
Handle = NativeLibrary.plc_tag_create(url, controller.Timeout);

I get an exception System.BadImageFormatException. 'An attempt was made to load a program with
an incorrect format. (Exception from HRESULT 0x8007000B')

please help

Hi Laz,

Were you able to find a solution for this issue?
I am experiencing the similar problem. I have tried other referenced wrappers and it works fine with ASP.NET Framework. I tried using this wrapper(ASP.NET Standard) on a new ASP.NET core application but with no luck.

Update: In order to fix the issue I had to use Dependency Walker to identify the missing dll that this wrapper/plctag.dll had dependency on. To fix the VC++ .dll file dependency I modified the Visual Studio to add Desktop Development using C++ (any other module that uses C++ can be added though).
