Powershell 找不到类型[Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]

我正在尝试对Powershell中指定流程参数的生成进行排队。我得到以下错误。。。知道我做错了什么吗

不是在GAC！您需要向GAC添加dll 或 试试这个

简单的。。。不是在GAC！吼叫声无论如何谢谢你。。。但是它解决了：-在一个带有VS2015和TFS Power工具的新的Windows 10机器上，使用Power Stand 2015，我惊讶地发现DLL不再在程序文件（x86）\VisualStudio版本下，而是必须从“C:\程序文件（x86）\微软Team Foundation Server 2015动力工具”中引用。这为我解决了同样的错误。

add-type -Path 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Workflow.dll'
