升级到TFS 2015后出现TF400898错误
将TFS Express 2013升级到2015年后，我收到以下错误：
1）当试图去tfs管理页面

3）在Visual Studio 2015中尝试连接时：
CData elements not valid at top level of an XML document. Line 1, position 3.
我该如何解决它？
我能找到的与此问题相关的唯一资源是MSDN论坛帖子。
我怀疑你试图安装Windows Server AppFabric，但还没有配置它。 如果您不使用Windows Server AppFabric，则应该卸载/取消配置它。
这个评论是有启发性的，但有点可怕，因为我实际上依赖于AppFabric！
然而，我只是使用缓存功能，事实证明AppFabric有一个整体的Service Management Service来拦截请求 - 或者这种情况。 我没有使用它。
因此，我能够卸载主机组件来解决问题。
Programs and Features AppFabric 1.1 for Windows Server选择AppFabric 1.1 for Windows Server然后单击Change Hosting Services 
继续点击Next删除此组件。
您现在应该能够运行TFS而不会与AppFabric发生冲突。
如果您实际使用的是Hosting Services您可能已经知道的比我如何运作更多，因此我希望您可以从那里拿到它来诊断问题。 原来的错误信息应该给出一些方向。
