Add WCF Reference to .Net 6

Question

I'm try to add this https://apps.ika.gr/WebServicesSepeNew-WebServicesSepe-context-root/WebServicesMainMethodSoap12HttpPort?wsdl WCF in an .Net 6 project through VS 2022 -> Add Service Reference -> WCF Service wizard.

I'm getting this warning

Cannot import wsdl:port\r\nDetail: \r\nXPath to Error Source: //wsdl:definitions[@targetNamespace='http://webservicessepe/']/wsdl:service[@name='WebServicesMainMethodService']/wsdl:port[@name='WebServicesMainMethodPort']

Add when its going to scaffolding service code its shows this error

Number of service endpoints found: 0
No code was generated.
If you were trying to generate a client, this could be because the metadata documents did not contain any valid contracts or services, or because all contracts/services were discovered to exist in --reference assemblies. Verify that you passed all the metadata documents to the tool.
Done.
ErrorFailed adding service reference(s). Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

If I try to added it in .net 4.6 framework and above its working correctly
Any ideas please?

Hi @Manos Kanellopoulos ,

First of all, according to the error information, please check whether there are valid contracts and services, and make sure that the names are corresponding.

Then check out this docs to see if the steps it takes to add a service reference are any different from the ones you added.

You can only post to the WCF repo and hope anyone there can give you a definite answer,

https://github.com/dotnet/wcf/issues

The error message is clear the "An unsupported security policy assertion was detected during the security policy", so asking on GitHub can tell you if any hope that security policy is going to be supported in the future.
