在uwp中使用sqlite实现实体框架中的组合键

public class MyEntity
{
    [Key]
    [Column(Order = 1)]
    public int Key1 { get; set; }

    [Key]
    [Column(Order = 2)]
    public int Key2 { get; set; }

    public string Name { get; set; }
}

public class MyDbContext : DbContext
{
    public DbSet<MyEntity> MyEntities { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlite("Data Source=mydatabase.db");
    }
}

using (var context = new MyDbContext())
{
    var entity = new MyEntity { Key1 = 1, Key2 = 2, Name = "Example" };
    context.MyEntities.Add(entity);
    context.SaveChanges();
}
