Can't generate proxy using WSDL file with "no valid endpoints" error

[petr-kirillov]

Trying to generate proxy using Travelport WSDL file in VS2017 using "Microsoft WCF Web Service Reference Provider" for my .NET Core or Standard project and hitting "The service at the following URI does not have any valid endpoints" error.

Below is the extraction from WSDL file (refer to Terminal.wsdl.zip for complete file).

There are endpoints defined in <soap:address> elements:

<?xml version="1.0" encoding="UTF-8"?> 

<definitions name="TerminalServices"
             xmlns="http://schemas.xmlsoap.org/wsdl/"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns:tns="http://www.travelport.com/service/terminal_v33_0"
             xmlns:ur="http://www.travelport.com/schema/terminal_v33_0"             
             xmlns:ns1="http://www.travelport.com/schema/terminal_v33_0"
             xmlns:common="http://www.travelport.com/schema/common_v33_0"             
             targetNamespace="http://www.travelport.com/service/terminal_v33_0">

    <service name="TerminalService">
        <port name="CreateTerminalSessionServicePort" binding="tns:CreateTerminalSessionServiceBinding">
            <soap:address location="http://localhost:8080/kestrel/TerminalService"/>
        </port>
        <port name="TerminalServicePort" binding="tns:TerminalServiceBinding">
            <soap:address location="http://localhost:8080/kestrel/TerminalService"/>
        </port>
        <port name="EndTerminalSessionServicePort" binding="tns:EndTerminalSessionServiceBinding">
            <soap:address location="http://localhost:8080/kestrel/TerminalService"/>
        </port>
    </service>

</definitions>

@petr-kirillov In the case of no valid endpoints, there should be more information on the last window you see. Could you copy and paste it here?

We will also take a look at the wsdl file.

Thanks, Hong Dai

@hongdai WSDL is attached https://github.com/dotnet/wcf/files/1239015/Terminal.wsdl.zip

and here is the screenshot from VS:

@petr-kirillov The wsdl file has problems. See below detailed messages:

I am facing a similar issue, can I know where did you get that log information from?

[hongdai]

@BladeWise Currently we do not always show the warning/error messages to the UI. You should be able to see the warning/error message by using dotnet-svcutil.dll directly: 1) find the path to dotnet-svcutil.dll 2) dotnet dotnet-svcutil.dll /tf:netcoreapp1.0 /Verbosity:Verbose

Thanks, Hong Dai

[BladeWise]

Using the dotnet-svcutil.dll everything is fine, and no error message is produced (I used /tf:netstandard20 without issues).
