Hi @InspiredUser33157 ,

Is there a way to capture the exact cmd line parameters used by Visual Studio 2019 when a Web Services is Added or Updated?

When you build a project or solution in Visual Studio, the entire command line used to run the compiler (csc.exe, including switches and parameters) is displayed in the Output window. If you don't see it there, check the Verbosity level by going to:
Options > Projects and Solutions > Build and Run > MSBuild project build output verbosity
and then copy the output, search cl.exe and link.exe.

How can I exactly mimic the exact svcutil command line parameters that VS2019 is using?

I do not quite understand you. Do you want to use Svcutil.exe or the command line of VS2019?
You can check the documentation for detailed instructions.

The Build and the Web Service update seem to be two different operation. The Web Service update seems not to use the Output window. Doesn't it call SVCUTIL.exe to create the Client Proxy files? And if so, what cmd line params is it using? I'm looking for those parameters so I can run from the cmd line in order to better troubleshoot my original issue of the Reference.cs not getting built.

Hi @InspiredUser33157 ,
First of all to generate proxy class we need to have our service up and running. So before using this utility make sure that your service is running without any issue.
After verifying the service status go to Visual Studio Command Prompt and run the following command.

svcutil http://localhost/MyService/Service.svc /Language=c# /t:Code /out:C:\Service\ServiceProxy.cs /config:C:\Service\ServiceProxy.config

it generates two files in C:\Service folder, the proxy file and config file,

So I don't have to add any of the other files to the cmd line parameters such as the Service.xsd, Service1.xsd, etc?

svcutil http://localhost:61394/BrokerWcf.svc /Language=c# /t:Code /out:"C:\Projects\MyWeb 3.x\MyWeb v3.x\MyWeb.Setup\Service References\BrokerWcfSvc\Resources.cs" /config:"C:\Projects\MyWeb 3.x\MyWeb v3.x\MyWeb.Setup\Service References\BrokerWcfSvc\ServiceProxy.config"

This produced no errors and generated a empty Reference.cs

When performing a Web Service Update in VS2019 I get the errors, but the cmd line doesn't show any errors.

Hi @InspiredUser33157 ,
First you have to make sure your web service is up and running.Then your cmd command should be wrong, I suggest you can look at the code I provided.
https://learn.microsoft.com/en-us/dotnet/framework/wcf/servicemodel-metadata-utility-tool-svcutil-exe

svcutil http://localhost/MyService/ClassName.svc /Language=c# /t:Code /out:ClassNameProxy.cs /config:ClassNameProxy.config

In above command you should replace the service URL ( http://localhost/MyService/Service1.svc) with the URL of your service.
/t:code will specify that the out put should be generated as code.
/out:ClassNameProxy.cs /config:ClassNameProxy.config parameters will tell the utility to name the files as specified in these parameter values. After you run the command, tool will generate the output file and config file.
After that just include the ClassNameProxy.cs file into your project and open the ClassNameProxy.config file and copy the entries to your web.config file. You may also need to update the ClassNameProxy.cs file and update the namespace as per the one that you are using in your project. After that you can easily reference the service in your code and call the operations.

Yes, when I perform that command line I get no errors or messages but the Reference.cs is still empty so I'm looking for a better way of troubleshooting this to get to the actual error. Any Ideas?

I'm using the following: svcutil http://MyWebweb.MyDomain.com/BrokerWcf.svc /Language=c# /t:Code /out:"C:\Users\csalerno.MyDomain0\Projects\MyWebWeb 3.x\MyWebWeb v3.x\MyWebWeb.Setup\Service References\BrokerWcfSvc\References.cs" /config:"C:\Users\csalerno.MyDomain0\Projects\MyWebWeb 3.x\MyWebWeb v3.x\MyWebWeb.Setup\Service References\BrokerWcfSvc\ServiceProxy.config"
It successfully produces the Reference.cs file but the async "completed" methods never get generated nor does the BrokerWcfSvc class. I get the "GetBrokersAsync()" but I don't get the GetBrokersCompleted event. Am i missing a command line switch to produce this?

Hi @InspiredUser33157 ,
Did you set the GetBrokersCompleted event on the server?
For example: public event Method2CompletedEventHandler Method2Completed;
For specific information, you can check the documentation: https://learn.microsoft.com/zh-cn/dotnet/framework/wcf/synchronous-and-asynchronous-operations#event-based-asynchronous-pattern

I finally achieved the correct svcutil cmd line syntax with one exception.

/ct:System.Collections.Generic.ObservableCollection`1

The Error: No type could be loaded for the value System.Collections.Generic.ObservableCollection`1 passed to the /collectionType option.

Anyone know the correct, acceptable syntax?
