尝试安装此软件包时，我似乎遇到了依赖问题。我试图弄清楚我搞砸了什么以及如何调试它，这样我就可以使这一切正常工作。奇怪的是，即使它说它未能添加对 System.Web.Http.OData 的引用，该引用也会在失败后出现在项目中。

我在 VS2012 之上安装的唯一东西就是这个更新。

编辑：

因此，似乎已经安装了上面的 Microsoft.AspNet.WebApi.OData 包。所以，我删除了那个。现在，当我尝试为 Breeze 安装需要上述库才能工作的软件包时，它会抱怨添加 System.Spatial 。

最后不得不卸载并重新安装 VS2012 才能阻止这种情况发生。不确定哪个依赖项搞砸了，但即使删除包并重做它们也无济于事。
