[NamanGajjar26]

in this case I am use microsoft.clearscript.v8 in asp .net core mvc this is below homecontroller.cs code

` public async Task<IActionResult> Index()
    {

        using (var engine1 = new V8ScriptEngine())
        {

            engine1.AddHostType(typeof(JavaScriptExtensions));

            engine1.DocumentSettings.AccessFlags = DocumentAccessFlags.EnableFileLoading;

            string scriptPath = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "js", "NewScript.js");

            string scriptContent = System.IO.File.ReadAllText(scriptPath);

            engine1.Execute(scriptContent);

            dynamic data = engine1.Evaluate("NewLinq();");

            return View();

        }
}`

and this below code in NewScript.js (JavaScript file) function

`function NewLinq() {

const rawData = [
    { "id": 1, "name": "John", "age": 25 },
    { "id": 2, "name": "Jane", "age": 30 }      
];

var result = rawData
    .filter(person => person.age > 25);  

return result;

}`

Hello @NamanGajjar26,

As with your previous sample, we tested your code and encountered no issues. Also, you aren't using Linq anywhere above, so we're not clear on how it's related.

in this code return UnderlyingSystemType = '((Microsoft.ClearScript.ScriptItem)data).UnderlyingSystemType' threw an exception of type 'System.NotImplementedException'

Again, where are you seeing this exception? How can we reproduce it? Can you provide a stack trace?

Thanks!
