When I am trying to run my application I am getting this exception

An exception of type 'System.ArgumentNullException' occurred in mscorlib.dll but was not handled in user code

In Global.asaxcs file in GlobalConfiguration.Configure(WebApiConfig.Register); line

Here is the code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Routing;

namespace Bot_Application2_test
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }
}

How to solve this?

I faced the same problem. In Solution Explorer -> Web.config . Make sure AppID & AppSecret is not null. { 

 <appSettings>
    <!-- update these with your appid and one of your appsecret keys-->
    <add key="AppId" value="YourAppId" />
    <add key="AppSecret" value="YourAppSecret" />
  </appSettings>

}

Hope it helps you!
