类库中的实体框架为空

Question

I have a potentially simple issue. My EF code obtains data in every project except one class library. Do I need an additional connection string in my App.config file for this class library? I have all data pulling from a class library called "models" with one connection string for the whole project. What do you suggest I do? Perhaps this is an issue with my local database too. Please let me know if you need more information.

Sample:

public static bool IsAdmin()
        {
            try
            {
                using (EmployeeContext _context = new EmployeeContext())
                {
                    string user = WindowsIdentity.GetCurrent().Name;

                    var adminCheck = (from u in _context.Administration where u.Login.Equals(user) select u).FirstOrDefault();

                    if (adminCheck == null)
                    {
                        return false;
                    }
                    else
                    {
                        return true;
                    }
                }
            }
            catch(Exception ex)
            {
                ErrorLogging.Record(ex.ToString(), ex.StackTrace);
            }
            return false;
        }

在主应用程序中定义连接字符串，问题可能是（尽管我不确定）EF默认为localDB。
