ASP.NET Core 6 ODATA Count not returning a value

I have recently upgraded to .NET 6 Core Preview and I am experiencing some issues with ODATA. What use to work in .NET Core 3.1 no longer works.

Here is my Startup snippet: I also believe EnableQueryFeatures() allows for Count by default.

services.AddControllers().AddNewtonsoftJson(options =>
    { 
        options.SerializerSettings.ContractResolver = new DefaultContractResolver();
    }).AddOData(opt => opt
          .EnableQueryFeatures()
          .AddRouteComponents("odata", GetEdmModel()
    );

I have the following Action Method and when called, the count is not returned to the front end.

The pageResult holds a count value, but is not being returned to the front end, when I inspect the result using Chrome DevTools.

[Route("odata/Tasks")]
public PageResult<TaskModel> AjaxListOData([FromQuery]ODataQueryOptions queryOptions)
{            
    var result = queryOptions.ApplyTo(dataContext.Tasks) as IEnumerable<TaskModel>;
    var pageResult = new PageResult<TaskModel>(
    result,
    null,
    count: Request.ODataFeature().TotalCount);

    return pageResult;
}

I resolved the problem by inheriting from ODataController and not from Controller.
