使用 powershell 从 Tfs 获取工作项存储

如何使用 powershell 从 TFS 获取 WorkItemStore？

我尝试过以下方法：

function get-tfs {

  param(
        [string] $ServerName = "http://MyServer:8080/tfs"
  )

  begin{}

  process
  {
        [psobject] $tfs = [Microsoft.TeamFoundation.Client.TeamFoundationServerFactory]::GetServer($serverName)
        return $tfs
  }
  end{}
}     

[Reflection.Assembly]::LoadFrom("C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.WorkItemTracking.Client.dll")

上面的代码执行得很好，我有一个 $tfs 的值。

然后我这样做：

   $wis = $tfs.GetService([Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore])

但 $wis 为空。如果我这样做，同样的事情：

   $wis = $tfs.TfsTeamProjectCollection.GetService([Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore])

另外，如果我这样做，powershell会说它找不到程序集“Microsoft.TeamFoundation.WorkItemTracking.Client”，即使它刚刚找到并在一秒钟前加载它： 添加类型 -AssemblyName Microsoft.TeamFoundation.WorkItemTracking.Client

我不明白为什么它找到了程序集却突然找不到了。

我究竟做错了什么？

这样的事情对我有用：

function get-tfs
{
    param([string] $ServerName = "http://myserver:8080/tfs")

    $binpath   = "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0"
    Add-Type -path "$binpath\Microsoft.TeamFoundation.Client.dll"
    Add-Type -Path "$binpath\Microsoft.TeamFoundation.WorkItemTracking.Client.dll"

    $creds = New-Object Microsoft.TeamFoundation.Client.UICredentialsProvider
    $teamProjectCollection = New-Object Microsoft.TeamFoundation.Client.TfsTeamProjectCollection $ServerName,$creds

    $ws = $teamProjectCollection.GetService([Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore])
    return $ws
}
