.net - Webmatrix 3.0 nuGet 关于 Net.Http 的投诉

Question

我刚刚安装了 WebMatrix 3.0。当我单击功能区上的 NuGet 扩展以加载一些扩展时，我收到一条错误消息，指出安装的 NuGret 版本(显然是 2.2)与 .Net.Http dll 的版本不兼容。我试过通过扩展管理器升级 NuGet，但似乎没有办法做到这一点 - 只有一个禁用和一个卸载选项。对这里发生的事情有什么想法吗？为什么与 WebMatrix 3.0 一起安装了不兼容的 NuGet 后退版本？

带有堆栈跟踪的错误消息如下:

An error occurred.

The schema version of 'Microsoft.Net.Http' is incompatible with version 2.2.31210.9045   of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.

我刚刚遇到了同样的错误消息。解决方案是清除 NuGet 包缓存并重试。
