查询ef core更简单

Question

我想知道是否有比以下简单示例更简单的查询ef core的方法。我想避免两次调用Test3以便包含Test3的所有所需属性：

public class Test1
{

}

public class Test2
{

}

public class Test3
{
    public Test1 Test1 { get; set; }
    public Test2 Test2 { get; set; }
}

public class Test4
{
    public Test3 Test3 { get; set; }
}

public class Test5
{
    public Test5(DataContext context)
    {
        var t = context.Test4
                .Include(o => o.Test3)
                    .ThenInclude(o => o.Test1)
                .Include(o => o.Test3)
                    .ThenInclude(o => o.Test2);
    }
}
