Steeltoe Refresh not working as expected(not reloading the config values without restarting application) in .NET core 3.1

Problems is not getting(updated) the latest config values without restarting the application.

//My Code is: 

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using System;
using Steeltoe.Management.Endpoint;
using Steeltoe.Management.Endpoint.Refresh;


//Startup class:
public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers();

    services.AddOptions();

    services.AddRefreshActuator();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseRouting();

    app.UseAuthorization();
    app.UseCustomSwagger();

    app.UseEndpoints(endpoints =>
    {
        endpoints.Map<RefreshEndpoint>();
        endpoints.MapControllers();
    });

}


//Controller class:

namespace DemoAppForRefresh.Controllers
{
    [ApiController]
    [Produces("application/json")]
    public class ReRouteController : ControllerBase
    {

        private readonly IConfigurationRoot _configuration;


        public ReRouteController(IConfigurationRoot configuration)
        {

            _configuration = configuration;

        }

        [HttpGet("v1/test")]
        public IActionResult GetTestValue()
        {

            return Ok(new { ConfigurationUrl = _configuration.GetValue<string>("vendor-route:url") });
        }
    }
}

If I change any configuration values while the application is running, it has no effect.

In other words that you can't get the most recent configuration values unless you restart the application.

So please help on this.

It looks like you've added the Refresh actuator correctly, but the actuator does not automatically refresh when your configuration changes. The refresh should now be triggerable via HTTP request - Have you issued a GET request to /actuator/refresh?
