Answer 1

错误表明您正在安装MvcSiteMapProvider.MVC4 NuGet package，但您的项目是MVC 5（因为它有Razor 3.2.2）。您必须将与您的MVC版本（在本例中为MvcSiteMapProvider.MVC5）匹配的软件包安装到您的项目中。

PM> Install-Package MvcSiteMapProvider.MVC5

请注意MvcSiteMapProvider NuGet package已过时，除非您打算使用MvcSiteMapProvider v3.x，否则不应将其安装到任何项目中。

如果您要从MvcSiteMapProvider v3升级到v4，请参阅upgrade guide。
