附加定义:对COM组件的调用已返回错误HRESULT E_FAIL [英] Buid definition: Error HRESULT E_FAIL has been returned from a call to a COM component

问题描述

当我向TFS中添加新工作项时，构建定义会引发如下异常:

When I add a new work item to TFS, build definition throw a exception as below:

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.如果可以的话，请帮助我！

推荐答案

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工作项.
4.他们通过WI ID搜索工作项.

This issue arises when:
1. They try to create a new work item – user story, bug, task etc.
2. They try to edit an existing query.
3. They try to open a work item from a query result set.
4. They search for a work item by the WI ID.

请尝试两种方法来解决此问题:

Please try two ways to resolve this problem:

1. 重新启动计算机服务器以安装TFS
   
2. 尝试删除路径如下的项目缓存:
   

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

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

然后运行"devenv.exe/setup"以重新构建缓存.
开始->运行-> C:\ Program Files \ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ devenv.exe/setup

Then run "devenv.exe /setup" to re-build the cache.
Start—>Run—> C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe /setup

我已经遇到了问题.我已经通过使用#1解决了它

I've faced with the problem. I've resolved it by use #1
