Question

当我向TFS添加新工作项时，构建定义会抛出异常，如下所示：

Exception Message: Error HRESULT E_FAIL has been returned from a call to a COM component. (type COMException)
Exception Stack Trace:    at Microsoft.TeamFoundation.WorkItemTracking.Client.DataStore.DataStoreNative.BeginDataStoreInit(IntPtr handle, String defaultCachePath, String instanceId, Int32 cacheVersion)

我无法确定根本原因。如果可以，请帮助我！

出现这个问题的时候：
1.他们尝试创建一个新的工作项 - 用户故事，错误，任务等。
2.他们尝试编辑现有的查询 3.他们尝试从查询结果集中打开工作项他们通过WI ID搜索工作项目。

请尝试两种方法来解决此问题：

重新启动计算机服务器以安装TFS
尝试删除路径喜欢的项目缓存：

C：\ Program Files \ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ ProjectTemplatesCache或
C：\ Program Files（x86）\ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ ProjectTemplatesCache

然后运行＆＃34; devenv.exe / setup＆＃34;重新构建缓存开始 - ＆GT;运行 - ＆GT; C：\ Program Files \ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ devenv.exe / setup

我遇到过这个问题。我使用＃1
