工作转移到新的TFS平台
打开source control在创建workspace时出错
信息为：
The Path <local path> is already mapped in workspace <machine name [old tfs server]>
很诡异的bug：）
Google搜索发现别人也遇到过相同的问题（估计是很多人遇到过）
参考Kevin Jones的博客文章，我们知道Client端的配置信息存储在
“C:/Documents and Settings/[user]/Local Settings/Application Data/Microsoft/Team Foundation/1.0/Cache/VersionControl.config”
不过让每个人修改config文件可不是个好的workaround
好在Buck Hodges给出了较为明确的解释：
The reason that you hit this is due to switching servers. Every server has a unique identifier, which is a GUID. Each local path can only be mapped in a single workspace. You originally had a workspace on the first server that used the local path you wanted to use with the new server. Let's say that's c:/projects. When you create the new workspace on the new server (GUID2) that you also want to map to c:/projects, the client sees that the old server (GUID1) is already using that local path. Since the IDs for the servers do not match, the client complains that c:/projects is already mapped to the old workspace on the old server.
并且有了明确的解决方法：
The solution is to clear the cache file, as described above. The problem will not occur if you upgrade the same server (i.e., you don't create a new server).
You can use the command "tf workspaces /remove:*" to clear out all of the cached workspaces (it only affects the cache file). You can specify /s:http://oldserver:8080 to just clear out the workspaces that were on the old server. The MSDN doc for the workspaces command are at http://msdn2.microsoft.com/en-us/library/54dkh0y3.aspx.
嘿嘿，打开VS2008的CMD，输入"tf worksapces /remove:* /s:http://oldserver:8080"
返回VS中的TeamExplorer发现还是不行
于是决定删除所有的cache中的workspace
"tf workspaces /remove:*"
再次返回TeamExplorer，一切OK了：）
多说一句，MSDN文档真的很烂，到现在了内容也不更新，还是要求输入/s:ServerName，
如果这样输入，会有个错误告诉你：URI非法，不能够识别URI的格式。
