How to solve a "HTTP Error 404.3 - Not Found" error?
提问by Wim ten Brink
Simple problem. I start up VS2008 and create a new WCF Service application. This will create a default application with a few test methods showing it works. I press CTRL+F5 and it does indeed work! Great! However, it uses the Visual Studio Development server, which I don't want to support.
简单的问题。我启动了 VS2008 并创建了一个新的 WCF 服务应用程序。这将创建一个默认应用程序，其中包含一些显示其有效的测试方法。我按 CTRL+F5 确实有效！伟大的！但是，它使用了我不想支持的 Visual Studio 开发服务器。
So I go to the project properties, switch to using a local IIS Web server, create the virtual directory and press CTRL+F5 again. And this "HTTP Error 404.3 - Not Found" error is greeting me back.
所以我转到项目属性，切换到使用本地 IIS Web 服务器，创建虚拟目录并再次按 CTRL+F5。这个“HTTP 错误 404.3 - 未找到”错误正在向我致意。
So something in my IIS7/Vista-64 setup is wrong. What could I be missing?
所以我的 IIS7/Vista-64 设置中的某些东西是错误的。我可能会错过什么？

The problem, however, is then to re-register ASP.Net to IIS, which is explained below.
然而，问题是将 ASP.Net 重新注册到 IIS，这将在下面解释。
And also if you're on a 64bit machine always use Framework64 paths: C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -iru
而且，如果您使用的是 64 位机器，请始终使用 Framework64 路径：C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -iru
Below is the explanation from Microsoft:

This error can occur when IIS is installed after installing .NET Framework 4, or if the 3.0 version of the WCF Http Activation module is installed after installing IIS and .NET Framework 4.
在安装 .NET Framework 4 后安装 IIS 时，或者安装 IIS 和 .NET Framework 4 后安装 3.0 版本的 WCF Http 激活模块时，可能会出现此错误。
To resolve this problem, you must use the ASP.NET IIS Registration Tool (Aspnet_regiis.exe,) to register the correct version of ASP.NET. This can be accomplished by using the –iru parameters when running aspnet_regiis.exe as follows:
要解决此问题，您必须使用 ASP.NET IIS 注册工具 (Aspnet_regiis.exe) 来注册正确版本的 ASP.NET。这可以通过在运行 aspnet_regiis.exe 时使用 –iru 参数来完成，如下所示：
aspnet_regiis.exe -iru
aspnet_regiis.exe -iru

I tried running ServiceModelReg and aspnet_regiis.exe with various flags and added HTTP Activation feature but it still didn't work. What finally worked was adding the following handler manually to my web.config file.
我尝试使用各种标志运行 ServiceModelReg 和 aspnet_regiis.exe 并添加了 HTTP 激活功能，但它仍然无法正常工作。最终起作用的是将以下处理程序手动添加到我的 web.config 文件中。
<system.webServer>
<handlers>
<add name="svc-Integrated" path="*.svc" verb="GET,HEAD,POST,DEBUG" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" modules="ManagedPipelineHandler" scriptProcessor="" resourceType="Unspecified" requireAccess="Script" allowPathInfo="false" preCondition="integratedMode" responseBufferLimit="4194304" />
My project was running .Net 3.5 and IIS was 7.5 and 7.0.
我的项目运行的是 .Net 3.5，IIS 是 7.5 和 7.0。
