Создадим класс Студент

namespace WpfApp3.model
{
    public class Student
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public int Course { get; set; }
        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[]{
            new Student{
                Age=24,
                Nation="Китаец",
                Course=4,
                Name="Хэй Вэнь"},
            new Student{
                Age=22,
                Nation="Русский",
                Course=2,
                Name="Семен Хомяк"},
            new Student{
                Age=19,
                Nation="Американец",
                Course=1,
                Name="Джейк Ли"}
        };
        }
    }
}

создадим класс Globals

namespace WpfApp3
{
    internal class Glocals
    {
    }
    class Globals
    {
        public static IDataProvider dataProvider;
    }
