tfs - 构建定义 : Error HRESULT E_FAIL has been returned from a call to a COM component

Question

当我向 TFS 添加新的工作项时，构建定义会抛出如下异常:

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，请你帮助我!

Answer 1

在以下情况下会出现此问题:
1. 他们尝试创建一个新的工作项——用户故事、错误、任务等。
2. 他们尝试编辑现有查询。
3. 他们尝试从查询结果集中打开一个工作项。
4. 他们通过 WI ID 搜索工作项。

请尝试两种方法来解决此问题:

重新启动机器服务器以安装 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“devenv.exe/setup”重新构建缓存。
开始—>运行—>C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe/setup
