Question

我正在尝试编写PowerShell脚本，但是遇到了错误。

当我的脚本到达该行时

$ tfs = [Microsoft.TeamFoundation.Client.TeamFoundationServerFactory] :: GetServer（$ server）

我得到了错误：

找不到类型[Microsoft.TeamFoundation.Client.TeamFoundationServerFactory] ...

InvalidOperation：（Microsoft.TeamF ... onServerFactory：TypeName）[]，RuntimeException

尽管我的问题与this question非常相似，但是我已经知道Microsoft.TeamFoundation.Client.dll文件及其依赖项在GAC中。另一个问题从来没有澄清过，我认为这可能会影响我将得到的答案。

在发生错误的那一行之前，我有许多Add-Type语句来确保我需要的引用在那里。这些语句中有一个指向Microsoft.TeamFoundation.Client.dll的Add-Type语句。我已验证它的位置正确。

我还包括了一条try-catch语句，该语句会在出现任何错误的情况下打印加载程序异常。当前，脚本可以成功通过这些语句，而不会触及catch块。

鉴于我知道相应的dll已存在于GAC中，什么可能导致此错误，以及如何解决该错误？

我建议您直接从目录加载程序集，例如：

 $TfsAssembliesPath="C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer"
    Add-Type -Path "$TfsAssembliesPath\Microsoft.IdentityModel.Clients.ActiveDirectory.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.ServiceBus.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.VisualStudio.Services.Common.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.VisualStudio.Services.WebApi.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.VisualStudio.Services.Client.Interactive.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Core.WebApi.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Common.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Client.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.TestManagement.Common.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.ProjectManagement.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Build.Client.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Build.Common.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Git.Client.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.SourceControl.WebApi.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.Client.QueryLanguage.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.Client.DataStoreLoader.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.Common.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.WebApi.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.Proxy.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.WorkItemTracking.Client.dll"
Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.TestManagement.Client.dll"
    Function CreateWorkItem{

    [string]$tfsCollectionUrl="TFS collection URL"
    [string]$tfsTeamProjectName="team project"

    $teamProjectCollection=[Microsoft.TeamFoundation.Client.TfsTeamProjectCollectionFactory]::GetTeamProjectCollection($tfsCollectionUrl)
    $ws = $teamProjectCollection.GetService([type]"Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore")
    $proj = $ws.Projects[$tfsTeamProjectName]

    $wit = $proj.WorkItemTypes["Task"]

    #Create a new work item of that type
    $workitem = $wit.NewWorkItem()

    $workItem.Title = "Sample Task Title 3"
    $workItem.Description = "Sample Description"
    $workitem.AreaPath = $tfsTeamProjectName
    $workitem.IterationPath = $tfsTeamProjectName

    $workItem.Save()
    Write-Host "The TFS work item number is: " $workItem.Id
    }

您还可以将程序集复制到特殊文件夹（例如当前项目中的Lib文件夹）

    $TfsAssembliesPath="$PSScriptRoot\Libs"
    Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Client.dll"
    Add-Type -Path "$TfsAssembliesPath\Microsoft.TeamFoundation.Common.dll"
...

我从没有使用过，但是我相信这会起作用。至少我没有收到找不到类型的错误。

using assembly Microsoft.TeamFoundation.Client
using namespace Microsoft.TeamFoundation.Client

$tfs = [TeamFoundationServerFactory]::GetServer($server)

并非如此，在PS 6中没有GAC。因此您必须将完整路径放置到dll才能使用程序集。

即使DLL已在GAC中，也找不到[Microsoft.TeamFoundation.Client.TeamFoundationServerFactory]
