没有声明“ package”元素

当使用 asp.net mvc 3项目与2010年相比，我有很多警告，如下:

我想知道我是否做错了什么，我需要更改一些东西，因为这是 Visual Studio 中的开箱即用项目。

警告1未声明“ package”元素。C: 用户 LUIS.SIMBIOS 文档 Visual Studio 2010 Projects SlnHR HR packages.config 22 HR

警告2验证(XHTML 1.0过渡) : 属性“ charset”不是元素“ meta”的有效属性。C: 用户 LUIS.SIMBIOS 文档 VisualStudio2010项目 SlnHR HR 视图 Shared _ Layout。Cshtml 411 HR

警告20错误6002: 表/视图‘ HR.dbo.vw _ aspnet _ Users’没有定义主键。键已经推断出来，并且定义是作为只读表/视图创建的。C: 用户 LUIS.SIMBIOS 文档 Visual Studio 2010 Projects SlnHR HRRazorForms Model HR.edmx 11 HRRazorForms
