I need to consume a SOAP 1.2 web service which uses WS-Security. The platforms I use at work are Delphi 10.2 Tokyo and .Net Core. Neither of these seem to work.
When trying with Delphi 10.2 Tokyo's built in WSDL importer (using SOAP 1.2 with Indy), my requests are sent without any SOAP header information. This invalid request throws the error Connection reset by peer.
When trying with .Net Core (using WCF Web Service Reference Provider) I get the error: System.PlatformNotSupportedException: 'TransportSecurityBindingElement.BuildChannelFactoryCore is not supported.'
Presumably due to the required feature not being supported by .Net Core yet: https://github.com/dotnet/wcf/blob/master/release-notes/SupportedFeatures-v2.0.0.md (Security.Message isn't supported)
Below is the WSDL. I have trimmed unnecessary XML from this file, and replaced the actual company name with Example. Hopefully this will give enough of an idea of what the WSDL policies/requirements are.

.NET Framework has full support for the SOAP service. I've developed a .NET Framework app in C#, and built a DLL which can be used by Delphi, .NET Core, etc. It's a bit of a roundabout solution, yet the easiest one I could find.
Accessing services in C#: https://learn.microsoft.com/en-us/dotnet/framework/wcf/accessing-services-using-a-wcf-client
Export DLL functions: Is is possible to export functions from a C# DLL like in VS C++?
