RavenDb，無法訪問文件，該文件被鎖定或正在使用

Question

這是個例外，現在完全讓我的生活變得很痛苦。不知道什麼改變了，但數據庫位於MVC3網站的App_Data文件夾中。該網站作爲默認網站託管在IIS 7.5中。

任何提示解決方法將受到歡迎。

編輯..這個問題可能是被扔在我的控制器代碼的異常後未清理或多或少相關，因此不調用dispose對文檔會議

慕尼黑涌泉，你需要確保您正確處理DocumentStore和DocumentSession生命週期管理。您應該在應用程序啓動時將DocumentStore作爲單例創建，並且應該在開始和結束請求時打開並處理會話。我建議爲OnBeginRequest和OnEndRequest編寫自己的處理程序。

請看官方示例應用程序RaccoonBlog，看看它是如何工作的。
