null reference exception on verified wsdl

[VVSoft]

Good day!

I ask for help with parsing wsdl, I am interested in extracting comments, but during processing I get a null reference exception error
wsdl_link: https://goznak.ru/bitrix/components/bitrix/forum.interface/show_file.php?fid=23900&action=download

i try parse as file in cmd:
.\SvcUtil.exe exchange.wsdl /svcutilConfig:configfile.xml

configfile.xml:

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="xmlComments" type="WCFExtrasPlus.Wsdl.Documentation.XmlCommentsConfig, WCFExtrasPlus"/>
  </configSections>
  <system.serviceModel>
   <client>
      <metadata>
        <wsdlImporters>
          <extension type="WCFExtrasPlus.Soap.SoapHeaderImporter, WCFExtrasPlus"/>
          <extension type="WCFExtrasPlus.Wsdl.Documentation.XmlCommentsImporter, WCFExtrasPlus"/>
        </wsdlImporters>
      </metadata>
    </client>
  </system.serviceModel>
  <xmlComments format="Default" wrapLongLines="True"/>
</configuration>

Result:

PS C:\Temp\123> .\SvcUtil.exe exchange.wsdl /svcutilConfig:configfile.xml

@devship are you still having this issue? I was going to troubleshoot, but the link to your WSDL no longer works.
