Question

I have a C# solution which consists of 2 projects: a console project and a asp.net web-api project (REST service); if I change a static property in a REST class from a REST client (ex. Fiddler), and right after I retrieve the value of this static property by using its getter from a console's class I obtain a different value (below the code). Any suggestions welcome !

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using RestLayer.Controllers;
using System.Web.Http;

namespace ValController
{
    class Program
    {
        static void Main(string[] args)
        {
            ....
                var t1 = Task.Factory.StartNew(() =>
                {
                    string stat = "disabled";

                    while (true)
                    {                    
                        System.Threading.Thread.Sleep(100);
                        var stat = ValuesController.getState();                 
                    }
                });
                t1.Wait();
                Console.WriteLine("t1 has completed.");  

        }

    }
}

The REST service:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using RestLayer.Models;

namespace RestLayer.Controllers
{
    public class ValuesController : ApiController
    {

        private static String state = "enabled";

        // POST api/values
        public IEnumerable<string> Post(Command command)
        {
            if (command.Instruction == "enableBV")
            {
                state = "enabled";

            }
            else if (command.Instruction == "disableBV")
            {
                state = "disabled";
            }
            return new string[] { "state", state };
        }

        public static String getState()
        {
            return state;
        }

        public static void setState(String newState)
        {
            state = newState;
        }

    }
}

The REST client I am using is Fiddler. In summary, the value of the var stat I retrieve in Program.cs is different from the one (state) I set by consuming the POST.

Static properties are only common to the current process. You have two processes here - a console app and a rest client.

To share the data between the two you could either persist the data to a database, but maybe better would be to have the console app make a call to the rest client and get the current state from it.

Your current "call to the rest client" just accesses the static property from the ValuesController class using import {LanguageForm} from '../components/LanguageForm';. To get the value from the rest client process you need to make a call to the rest api process using WebClient (or similar).
