NuGet程序包管理器控制檯無法加載PowerShell

Question

執行從Windows 7 Pro到8 Pro的就地升級之後，我一直無法使NuGet的程序包管理器控制檯在Visual Studio 2012 Pro中運行。我收到的錯誤是：

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\WINDOWS\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2977) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

The term 'Get-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. 

...我已經尋找過去幾天的方式來解決這個問題，但已經快到了完全是空的。我已經嘗試了所有的這些有沒有效果：

• 禁用所有Visual Studio附加功能
• 重置所有設置
• 重新安裝Visual Studio中
• 修復的Visual Studio
• 的Visual Studio之前開始的PowerShell（不這只是意味着啓動PowerShell，然後啓動Visual Studio？）
• 以管理員身份運行PowerShell和Visual Studio
• 在運行Visual Studio在安全模式下
• 設置電源外殼ExecutionProperty無限制

Visual Studio中已經表現出其他奇怪的行爲，如持續崩潰，而試圖添加Click事件的特定頁面的XAML爲好，正因爲如此，我的直覺認爲它不是Power Shell或NuGet，而是我的OS/Visual Studio的一個問題。

除非有人有解決方案，我想我只是做一個乾淨的Windows 8安裝，並希望修復它。

我發現這個問題，這是你的差不多：

Embedding Powershell v2.0 in .NET app on Windows 8 RTM

你可以嘗試對這個問題進行解決，看它是否解決了嗎？
