我刚刚将 TFS 从 2012 升级到 2013 年，构建定义不再有效。
我们的解决方案中有一些 Silverlight 5 项目，这些项目在开发计算机上构建良好，并且也用于在 TFS 2012 上构建，但现在失败了。我还安装了VS 2013，Silverlight开发人员运行时和Silverlight 5 SDK。
失败的任务是 ValidateXAML，下面是一段 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。不能 加载文件或程序集"System.Core，版本=5.0.5.0，区域性=中性，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。（HRESULT的例外：0x80131040）
完成执行任务"验证Xaml" -- 失败。（任务 ID：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求它，它给了我这个：

关键行是第一个 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所在的地方，但它说它在应用程序库之外。
我从未遇到过类似的事情，我的搜索也无处可去。已经追了好几天了，有人有解决方案吗？
尝试在
生成定义中强制 MSBuild 平台使用 X86，它应该可以解决你的问题。
希望对您有所帮助。
