In Visual Studio (C#, WinForms) I want to add a Service Reference from a *.wsdl file.
The underlaying *.xsd file imports other *.xsd files, one or more containing a <!DOCTYPE... DTD.
The 'Add Service Reference' function does not succeed and shows this error:
DTD is prohibited in this XML document.
How can I add the service reference?
To reproduce my problem:
Download the .wsdl files from:
https://github.com/gematik/api-telematik/tree/OPB5
The .wsdl file I want to add is located in: conn\phrs\PHRService_V2_0_2.wsdl
The *.dtd files are located in .\ext
