How do I fix SvcUtil generating code with errors in it for a C++/CLI WCF client?

Question

I've run into a problem with code generated by SvcUtil when generating a WCF client in C++/CLI.

When I run "SvcUtil.exe /t:code /l:cpp http://localhost:2772/mex/" it generates a header file containing the client class below.

[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;
};

This results in a lot of errors, which I would not have expected given it is generated code.

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'

Any suggestions on what I need to change or add to correct this? Should I just add an implementation for the listed interface methods?

Since the link is broken you can use Wayback Machine to see the page

The relevant part from the post is

You should use the following workaround to get a successful compile: Locate the full runtime assembly in: %SysRoot%\Microsoft.NET\Framework\v4.0.30319\System.ServiceModel.dll

Copy this dll.

Replace the Reference Assembly in: %ProgramFiles(x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.ServiceModel.dll

Recompiling your project should now succeed.

Alternatively, just add required TargetFrameworkVersion in .vcxproj

example: edit your .vcxproj to add TargetFrameworkVersion tag containing v4.7.2 within PropertyGroup at Globals scope

This should work without manually copying any dll.
