如何从现有的 WSDL 和 XSD 文件生成 WCF 服务主机

Question

我有来自我们的服务器之一的现有 WSDL 和 XSD 文件，该服务器使用 WAS（Windows 激活服务）运行 IIS 8 和 ASP.NET 4.5。 我正在为该项目使用 VS 2012。 我没有 WCF 服务主机的原始代码，所以我需要从现有的 WSDL 和 XSD 文件创建 WCF 主机。

我已经有了客户端代理代码，即客户端已完成。

我需要从现有的 WSDL 和 XSD 文件生成将托管在 IIS 8 服务器中的 WCF 服务主机吗？ 不是客户端代理代码 - 我已经完成了。

我有以下文件

1. myMainService.wsdl
2. mySubService.wsdl
3. myFirstXSD.xsd
4. mySecondXSD.xsd
5. myServiceSingleWSDL.wsdl
6. 客户端代理代码（完成）
7. 测试客户端（完成）

注意：MyMainService.wsdl 指向包含调用 myFirstXSD.xsd 和 mySecondXSD.xsd 的代码的 mySubService.wsdl 我也有单个 WSDL，即 myServiceSingleWSDL.wsdl

我通读了如何使用 SvcUtil.exe 和 Disco.exe，但我不确定如何正确使用。 大多数相似的问题都没有回答问题，而只是绕过它。

如果您可以包含用于执行此操作的命令，请提供分步说明。 任何帮助将不胜感激。

因此，我运行以下命令以从上述文件 SvcUtil /mc /language:C# /out:IService1.cs /n:*,Contoso.WcfServiceHost MyMainService.wsdl MySubService.wsdl MyFirstXSD.xsd MySecondXSD.xsd 生成以下代码

从这里开始下一步是什么？ 生成将托管在 IIS 8 中的 WCF 服务主机，以便客户端可以连接到它或使用它

这里生成的 Web.config 文件

      <?xml version="1.0" encoding="utf-8"?>
    <configuration>
      <system.serviceModel>
        <bindings>
          <wsHttpBinding>
            <binding name="WSHttpBinding_IMyService">
              <security mode="None" />
            </binding>
          </wsHttpBinding>
        </bindings>
        <client>
          <endpoint address="http://contoso.com/MyService.svc"
            binding="wsHttpBinding"  bindingConfiguration="WSHttpBinding_IMyService"
            contract="IMyService" name="WSHttpBinding_IMyService">
            <identity>
              <dns value="localhost" />
            </identity>
          </endpoint>
        </client>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"   multipleSiteBindingsEnabled="true"></serviceHostingEnvironment>
      </system.serviceModel>
     </configuration>

下面是生成的 Iservice1.cs 文件

svcutil.exe 不会为您生成服务代码（听起来您已经发现了）。

如果原始服务由您/您的公司创建或拥有，或者您拥有源代码的其他合法权利，您可以使用Reflector 、 JustDeCompile或类似工具（Reflector 有免费试用但您必须为长期使用付费，JustDecompile 是免费但不如 Reflector 灵活）来对 DLL/EXE 进行反向工程（假设您可以访问 DLL/EXE）。

如果这不是您的选择，您可以研究合同优先开发，尽管我自己从未使用过它：

使用 Windows Communication Foundation 进行基于架构的开发

我还看到了对 Thinktecture 的 WSCF.blue 的引用，这可能值得一看。
