Buid定义:错误HRESULT E_FAIL已从调用COM组件返回

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:

1. 重新启动计算机服务器以安装TFS
   
2. 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

我遇到了这个问题.我用#1解决了它
