How to get the current ASP.NET core controller method name inside the controller using Reflection or another accurate method

I want to get the current method name of my ASP.NET Core controller

I have tried getting the method name through reflection

    [HttpGet]
    public async Task<IActionResult> CreateProcess(int catId)
    {
        string methodName = System.Reflection.MethodBase.GetCurrentMethod().Name;

but this gives me a value of MoveNext and not CreateProcess

Take note I don't want to use the ViewContext

string methodName = ActionContext.RouteData.Values["action"].ToString();

as I lowercase my urls via the startup settings.The above will get me createprocess instead of CreateProcess

I preferably want an easy one liner as not a multiline extension method.
