我刚刚将 TFS 从 2012 升级到 2013，构建定义不再有效。
我们的解决方案中有一些 Silverlight 5 项目，这些项目在开发机器上构建良好，并且也用于在 TFS 2012 上构建，但现在它失败了。我还安装了 VS 2013、Silverlight 开发者运行时和 Silverlight 5 SDK。
失败的任务是 ValidateXAML，这是一段 MSBuild 日志文件：
C:\Builds\4\path\to\project\Shared\PresentationUtility\Controls\AssetListControl.xaml：错误：无法解析引用程序集。请检查参考程序集。无法加载文件或程序集 'System.Core, Version=5.0.5.0, Culture=neutral, ublicKeyToken=7cec85d7bea7798e' 或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。（来自 HRESULT 的异常：0x80131040）
完成执行任务“ValidateXaml”——失败。（TaskId：1514）在项目“PresentationUtility.csproj”中完成构建目标“ValidateXaml”——失败。：（TargetId：2112）
当然，System.Core 以正确的版本存在于服务器上的正确位置，所以我使用绑定日志查看器来追踪它，它给了我这个：

关键是第一个 WRN：
WRN: Not probing location file:///C:/Program Files (x86)/Reference Assemblies/Microsoft/Framework/Silverlight/v5.0/System.Core.DLL, because the location falls outside of the appbase.
这实际上是 System.Core 所在的位置，但它说它在应用程序库之外。
我从来没有遇到过类似的事情，我的搜索让我无处可去。这几天一直在追，有人有解决办法吗？
