Question

有很多问题在回答这个问题，但没有一个答案对我有用。

最初，当我尝试PUT或DELETE（可能还有其他动词）时，我得到的是405。看一些问题，解决方案似乎是改变处理程序映射。

我更改了以下内容：

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

我注意到动词已经在One of the following verbs框中了，所以在绝望中我将其改为接受所有动词。

现在，我甚至无法加载网页，更不用说像DELETE那样发出任何异国情调的请求了，我立即得到一个黄色的死亡屏幕：

Server Error in '/' Application.

到目前为止，我有：

通过Web PI安装了经过检查的ASP.NET 4.5
正在运行dism /online /enable-feature /featurename:IIS-ASPNET45
正在运行"%WINDIR%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r
正在运行C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis -I
比我能做的更多iisreset
替换ServiceModel中的applicationHost.config：

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

替换为：

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

我还能做什么，或者我应该在哪里看？

Answer 1

您还必须使用激活servicemodel 4.0 dism / online / enable-Feature / all / FeatureName：WCF-HTTP-Activation45

和de IIS管理器（服务器 - ＆gt;功能 - ＆gt;模块）检查是否看到servicemodel 4.0然后删除servicemodel。

Answer 2

在我的计算机上安装Synfusion Essential Studio后，我遇到了同样的问题。我通过执行以下步骤解决了这个问题：

打开IIS管理器控制台
在“服务器”面板上，转到“模块”，“功能视图”
确保ServiceModule-4.0在那里。如果不存在，请执行上述（1-6）
删除ServiceModel模块

Answer 3

想到这可能对某人有帮助。

如果在运行IIS的计算机上有多个版本的.NET Framework，并且在.NET Framework 4.0之后或Windows Communication Foundation中的服务模型注册之前安装了IIS，则会发生此错误。

Answer 4

此链接适用于我。

http://www.codeproject.com/Articles/613812/Solve-IIS-Error-Could-not-load-type-System-Servi

您必须删除ServerModel模块和svc集成处理程序。

Answer 5

将此添加到我的应用程序的 web.config 对我有用：

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        <add name="ServiceModel-4.0" type="System.ServiceModel.Activation.ServiceHttpModule, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" preCondition="managedHandler" />
    </modules>
</system.webServer>
