Could we have ActionFilter extends Enum<T> asp core2

I am new to Asp Core, and I tried to implement an IActionFilter that extends an Enum Type

public class IndexFilter<T> : IActionFilter
{
    public void OnActionExecuting(ActionExecutingContext context)
    {
          // for example T.GetType.GetProperties
    }
}

And in the controller

public class CategoryController : Controller
{
    [Route("")]
    [HttpGet]
    [ServiceFilter( typeof( IndexFilter<Category> ))]
    public async Task<IActionResult> Index()
    { 
          //  Code
    }
    ....
}

I gave it a shot and I stumbled over an Exception

An unhandled exception has occurred while executing the request.
System.InvalidOperationException: No service for type 'AuthWebApi.Filters.IndexFilter`1[AuthWebApi.Models.Entities.Category]' has been registered.
   at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService(IServiceProvider provider, Type serviceType)

I tried to change Startup.cs to :

services.AddScoped<IndexFilter<CategoryParent>>();
services.AddScoped<IndexFilter<Object>>();
services.AddScoped<IndexFilter<>>();

and nothing worked, unless I set IndexFilter to match the Controller:

services.AddScoped<IndexFilter<Category>>();

Which makes the Enumerable class acts like a normal class.

You could register IndexFilter<T> with generic type like below:

services.AddScoped(typeof(IndexFilter<>));

Then, it will be able to resolve the service:

[ServiceFilter(typeof(IndexFilter<Category>))]
public async Task<IActionResult> Category()
{
    return Ok();
}
[ServiceFilter(typeof(IndexFilter<CategoryParent>))]
public async Task<IActionResult> CategoryParent()
{
    return Ok();
}
