Visual studio 2015 从2012年迁移后TFS 2015生成出现错误

我们已经从TFS 2012迁移到TFS 2015，迁移后我们的构建无法工作。我们得到以下错误。 我在网上找不到太多关于这个的信息。 请帮忙

检查定制的XAML文件，确保删除对

Version=11.0.0、PublicKeyToken=123445

的任何引用。只要用简单的名字来提到这个程序集就行了。这允许Team Build加载与生成服务器版本匹配的版本

如果幸运的话，旧的定制是二进制兼容的，但是在最坏的情况下，您需要根据当前版本的TFS客户机对象模型重新编译它们

另见：

TFS 2015在构建服务的配置中发布了不正确的绑定重定向；TFSBuildServiceHost.exe.config

<dependentAssembly>
  <assemblyIdentity name="Microsoft.TeamFoundation" 
                    publicKeyToken="b03f5f7f11d50a3a" 
                    culture="neutral"/>
  <bindingRedirect oldVersion="10.0.0.0-12.9.0.0" newVersion="14.0.0.0"/>
</dependentAssembly>

这里需要注意的是，您正在运行TFS 2012的相同基础结构上运行TFS 2015构建服务（或者至少安装了相同的依赖项），Microsoft.TeamFoundation.dll是随Visual Studio 2012及之前的版本一起分发的

<dependentAssembly>
  <assemblyIdentity name="Microsoft.TeamFoundation" 
                    publicKeyToken="b03f5f7f11d50a3a" 
                    culture="neutral"/>
  <bindingRedirect oldVersion="10.0.0.0" newVersion="11.0.0.0"/>
</dependentAssembly>
