如何修复为 C++/CLI WCF 客户端生成错误的 SvcUtil 代码？

Question

在 C++/CLI 中生成 WCF 客户端时，我遇到了 SvcUtil 生成的代码问题。

当我运行“SvcUtil.exe /t:code /l:cpp http://localhost:2772/mex/”它生成一个包含下面客户端类的头文件。

[System::Diagnostics::DebuggerStepThroughAttribute, 
System::CodeDom::Compiler::GeneratedCodeAttribute(L"System.ServiceModel", L"3.0.0.0")]
public ref class DemoClient : public System::ServiceModel::ClientBase<IDemo^ >, public IDemo
{

    public: DemoClient();
    public: DemoClient(System::String^  endpointConfigurationName);
    public: DemoClient(System::String^  endpointConfigurationName, System::String^  remoteAddress);
    public: DemoClient(System::String^  endpointConfigurationName, System::ServiceModel::EndpointAddress^  remoteAddress);
    public: DemoClient(System::ServiceModel::Channels::Binding^  binding, System::ServiceModel::EndpointAddress^  remoteAddress);
    public: virtual System::String^  GetDemoString() sealed;
};

这会导致很多错误，这是我没想到的，因为它是生成的代码。

Demo.h(41): error C3766: 'DemoClient' must provide an implementation for the interface method 'void System::ServiceModel::ICommunicationObject::Closed::add(System::EventHandler ^)' : see declaration of 'System::ServiceModel::ICommunicationObject::Closed::add'

关于我需要更改或添加哪些内容来纠正此问题有什么建议吗？我应该只添加列出的接口方法的实现吗？

Answer 1

由于链接已损坏，您可以使用 Wayback Machine 查看页面

帖子中的相关部分是

您应该使用以下解决方法来成功编译：
在以下位置找到完整的运行时程序集：
%SysRoot%\Microsoft.NET\Framework\v4.0.30319\System.ServiceModel.dll

复制此 dll。

将参考组件替换为：
%ProgramFiles(x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.ServiceModel.dll

重新编译您的项目现在应该会成功。

Answer 2

中添加所需的 TargetFrameworkVersion

或者，只需在 .vcxproj示例 ：
编辑 .vcxproj 以添加包含 v4.7.2 的 TargetFrameworkVersion 标记
在全局范围内的 PropertyGroup 内

这应该可以工作，而无需手动复制任何 dll。
