随着.NET Core 2.2的发布,我希望能够在我们的Microsoft托管的DevOps(Azure)管道中构建这样的项目.但恢复步骤失败,说不支持2.2:

public class Person {
public PhoneNumber Phone { /* Some clever get/set logic here */ }
private string _phoneNumber; // Backing field
}
还是可以让PhoneNumber将自身存储为字符串？如果我只是通过删除上面的后备字段将其包括在模型中，则EF会被构造函数（一个受保护的ctor，具有比一个字符串多的args）和一个副本ctor混淆PhoneNumber(PhoneNumber other)。我可以让EF以某种方式忽略这些吗？
我愿意接受...
