Empty proxy generated from dotnet-svcutil

[coxp]

Describe the bug
Generating a proxy with dotnet-svcutil results in a proxy with service operations that contain no input or output parameters.

To Reproduce
Steps to reproduce the behavior:

1. dotnet-svcutil -ntr -syn "https://lms.landmarkinfo.co.uk/rrs/services/RRServicePlus?WSDL"
2. Generated Reference.cs proxy is invalid.

Expected behavior
A valid proxy generated with service operations that contain input and outputs.

Additional context
These two issues seem to be related but were marked as fixed in v1.0.2.

WSDL - RRServicePlus.txt

The SOAP fault definitions in the provided WSDL are invalid, causing errors that mislead the tool into generating incorrect code when the -syn option is used. The following workarounds can help resolve this issue:

1. Fix the Service/WSDL: Remove all nodes related to <fault name="ServiceUnavailableException">, then rerun the repro command. This will allow the tool to generate the proxy code without errors or warnings and prevent issues with operations missing inputs or output.
2. Avoid Using the -syn Option: By omitting the -syn option, the tool will follow an alternative code path, bypassing the issue (you will still see warning outputs related to the fault definitions in the WSDL). This allows asynchronous methods with parameters to be generated correctly.
