如何使用提升的權限從WiX運行ngen？

Question

我正在嘗試使用this article將ngen添加到我的安裝程序中。我想在安裝過程中同步運行ngen（優先級= 0），但它需要管理權限才能運行。所以，現在我已經在日誌中以下消息：

有沒有簡單的方法來詢問用戶的管理權限（使用標準的UAC提示），在這一刻，當NGEN開始？如果用戶按「否」，我想繼續沒有ngen。如果是 - 運行ngen並預編譯我的應用程序。 有什麼想法？

謝謝。

WiX已經運行提升的NGen自定義操作（Execute =「deferred」Impersonate =「no」）。您的.msi包必須是每臺機器才能運行它們。
