我正在使用 MetadataType 为我的实体提供两个独立实体的验证功能。需要注意的是，我正在使用一个客户端向导，该向导使用 jQuery 和 JavaScript 进行不显眼的验证。验证似乎适用于一个实体，而不适用于另一个。

经过进一步分析，我注意到未为未验证的实体呈现 data-val="true"。这是令人困惑的地方，Display 属性不适用于任一实体，随后仅呈现属性名称而不是 display 属性。我不明白。我一直在互联网上搜索任何遇到此问题但空白的人。

我对 jquery stepy 插件有同样的问题。我解决了当用户更改页面时添加验证规则的问题。

我终于找到了问题和解决方案。有多个问题。1) 我的实体与 web 项目位于一个单独的项目中，部分不能跨越多个项目。通过从实体类进行部分继承来修复该问题。2) 修复此问题后，我开始收到密码字段的 jquery 错误。显然，jquery.unobtrusive.validate 在 mvc3 命名和 Compare 属性方面存在问题。我必须按照本文所述对 .js 文件进行修复：比较（密码）属性。在这些更改之后，事情似乎正常工作。
