        public string Nation { get; set; }
        public string Photo { get; set; }
    }
}
```
## создадим интерфейс IDataProvider
```
namespace WpfApp3.model
{
    internal interface IDataProvider
    {
    }
}
```
## класс LocalDataProvider
```
namespace WpfApp3.model
{
    public class LocalDataProvider : IDataProvider
    {
        public IEnumerable<Student> GetStudents()
        {
            return new Student[]{

                Name="Джейк Ли"}
        };
        }
    }
}
```
## создадим класс Globals
```
namespace WpfApp3
