IIS8：無法加載類型'System.ServiceModel.Activation.HttpModule'

Question

有很多問題回答這個問題，但沒有答案爲我工作。

最初，當我試圖對PUT或DELETE（可能還有其他動詞）時，我得到了405。看一些問題，解決方案似乎是改變處理程序映射。

我改變了以下內容：

ExtensionlessUrlHandler-ISAPI-4.0_32bit 
ExtensionlessUrlHandler-ISAPI-4.0_64bit 
WebDAV 

我注意到動詞已經在One of the following verbs箱，所以在絕望中我改變了它接受所有動詞。

現在，我甚至無法加載網頁，更不用說像DELETE任何奇異的請求，我立即得到死亡的黃屏：

Server Error in '/' Application.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18045 

到目前爲止，我有：

1. 經過ASP.NET 4.5通過Web PI安裝
2. 運行dism /online /enable-feature /featurename:IIS-ASPNET45
3. 運行"%WINDIR%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r
4. 運行C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis -I
5. 更多iisreset比我能可能

6. 在applicationHost.config更換ServiceModel：

   <add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler" />

替換：

<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler,runtimeVersionv4.0" /> 

我還能做什麼，或者我應該在哪裏看？

感謝

Answer 1

你也要/在線激活servicemodel 4.0 DISM /使能功能/所有/ FeatureName：WCF-HTTP-Activation45

，並在德IIS管理器（服務器 - >功能 - >模塊） 檢查是否看到servicemodel 4.0，然後刪除servicemodel。

Answer 2

在我的計算機上安裝Synfusion Essential Studio後，我遇到了同樣的問題。 我決定通過執行以下步驟：

1. 打開IIS管理控制檯
2. 在Server面板到模組，功能視圖
3. 確保ServiceModule-4.0是存在的。如果它不存在，執行上述（1-6）規定的步驟
4. 刪除ServiceModel模塊

Answer 3

只是想這可能幫助別人。

如果運行IIS的計算機上有多個.NET Framework版本，並且在.NET Framework 4.0或Windows Communication Foundation的服務模型註冊之前安裝了IIS，則會發生此錯誤。

Answer 4

此鏈接適用於我。

您必須刪除ServerModel模塊和SVC集成的處理器。
