    my code as below by using csharp and i using asp.net core 2.2 web api

    public string PostUserLogin(string UserId, string Password)
       {
           DataAccess.CurrentDataBase = DataAccess.Credentials.SecurityDB;
           //================
           if (!string.IsNullOrEmpty(UserId))
           {
               DbParameter[] parameters = UserManager.CreateLoginParameters(UserId,Password);
               //:: Check For PassWord Validation days
               DataTable dt = DataAccess.ExecuteDataTable(SqlFactory.Queries.Userss_ValidatePasswordDays(), parameters);
               DataRow PassWordDays;
               if (dt.Rows.Count > 0) PassWordDays = dt.Rows[0];
               else PassWordDays = null;


               if (PassWordDays != null)
               {
                   if (!string.IsNullOrEmpty(PassWordDays["PasswordDate"].ToString()) && !string.IsNullOrEmpty(PassWordDays["PWDays"].ToString()))
                   {
                       if (Convert.ToInt32(PassWordDays["PWDays"].ToString()) > 0)
                       {
                           if (Convert.ToDateTime(PassWordDays["PasswordDate"].ToString()).AddDays(Convert.ToDouble(PassWordDays["PWDays"].ToString())).ToOADate() < DateTime.Now.ToOADate())
                           {


                           }
                       }
                   }
               }

               //==============
               bool IsUserValid = UserManager.IsValidUser(UserId, Password);
               if (IsUserValid)
               {
                   DataAccess.Credentials.SystemUserID = UserId;
                   DataTable dtGetBranches = DataAccess.ExecuteDataTable(
                           SqlFactory.Queries.Users_GetBranches(
                                                       DataAccess.Credentials.SystemUserID));
               }
               else
               {
                   string.Format("Invalid User Name {0} Or Password {1}",UserId,Password);
               }

           }
       }

    Hi engahmedbarbary,

    Asp.Net core don't need services to be defined with interfaces as WCF. You can create a simple API controller and return custom JSON result, if you want to expose a RESTful API.

    .Net core also support dynamic data type, so you can change your response as you want.

    public class AuthunticationController:ControllerBase
{
    public IActionResult Authenticate(string username, string password)
    {
       //your code for validation
 
       //case 1
       return OK(new {status:0, message:"your message"});
       
       //case 2
       return OK(new {status:1, message:"Your message", data:yourData});
    }
}
