找不到包“Microsoft.AspNetCore.Antiforgery”的编译库位置

Question

我正在使用 ASP.NET Core 1.1.0 开发 Web 应用程序。我的应用程序使用 IIS Express。但是当我将应用程序部署到 IIS 时，出现错误“找不到包'Microsoft.AspNetCore.Antiforgery'的编译库位置”。

我已从 project.json 中删除 preserveCompilationContext，但我得到“缺少一个或多个编译引用。可能的原因包括应用程序的“buildOptions”下缺少“preserveCompilationContext”属性project.json.”错误消息。

静态文件（如 .html）运行良好。

我该如何解决这个问题？

Answer 1

返回preserveCompilationContext，也许吧？

Answer 2

看起来您的 project.json 不包括您项目的所有依赖项，这可能解释了为什么在您的部署目标上找不到这些库 - 您是如何部署到 IIS 的，您能否确认所有是否包含所需的 DLL？

Microsoft.AspNetCore.Mvc 取决于：
Microsoft.AspNetCore.Mvc.Razor 取决于：
Microsoft.AspNetCore.Mvc.ViewFeatures 取决于：
Microsoft.AspNetCore.Antiforgery

preserveCompilationContext 用于编译您的 MVC 视图，它还可能引用 AntiForgery 库的内容，以在您网站上的任何表单上生成所需的令牌和 cookie。
