ASP.NET AJAX無法在.NET 3.5的本地主機上工作

Question

實時應用程序已部署一段時間並正常工作。應用程序池是v2.0 Classic。它位於Windows Server 2008 R2上。

我的本地環境是Windows 8.1。我在IIS Express中進行調試。瀏覽器開發人員工具中出現以下錯誤：

• 未捕獲的錯誤：ASP.NET Ajax客戶端框架未能加載。
• 未捕獲的ReferenceError：SYS沒有定義

所有的ScriptResource.axd的GET請求導致404錯誤。任何關於修復.NET Ajax的想法？

順便說一句，我已經完成了我以前見過的關於如何解決這個問題的所有建議，特別是處理程序。我有以下web.config。

我已經仔細檢查了IIS Express的applicationhost.config中的AXD處理程序。看來我有.NET 2.0 AXD處理程序。 （但我在解釋這些小知識。）

Answer 1

固定。問題不在於我的web.config。事實上，我找不到任何我的文件或代碼的問題。最終，我不得不重新創建項目並複製我的文件。具體來說，按順序：

1. 創建新的空白ASP.NET項目。 （Visual Studio默認爲4.5。）
2. 將目標框架更改爲版本3.5。
3. 複製當前項目中的代碼文件。
4. 在新項目的項目屬性中，確保新項目的程序集名稱和根名稱空間與現有項目的名稱空間匹配。
5. 在新項目中添加必要的參考。
6. 在調試模式下運行新項目，對其進行測試，確認所有工作正常。
7. 所有內容複製回來，覆蓋舊的項目，要注意以下幾點：
   1. 沒有必要覆蓋舊的解決方案（在我的情況，反正）。
   2. 一定要覆蓋舊的VS proj文件和bin文件夾。
   3. 我使用Git進行源碼控制，所以它會自動選取任何新/不同的文件，並忽略其他文件。
8. 在我的情況下，有兩種可能性（我能想到）是問題的根源。我不知道哪一個是真正原因：
   1. 我失蹤/My Project/MyExtensions/MyWebExtension.vb。
   2. vsproj文件中的某些東西。

Answer 2

由於網站被配置爲運行在.NET 2.0（或可能3.5），你需要在你的bin安裝AJAX控件工具包的DLL，因爲它們是可能安裝到生產服務器上的GAC，這就是爲什麼它在那裏工作。爲了能夠加載2.0 DLL，您需要將DLL安裝到計算機上的GAC中，或將它們包含在bin目錄中。 This answer應該有幫助。
