BizTalk 2010 - Unable to Import WSDL created in ASP.Net Core 2.1 (Failed to get metadata)

Question

WSDL service was created using ASP.Net Core 2.1

When I add reference to WCF service I get error message:

Metadata not available 
Failed to get metadata from "http://xxx.xxx.xxx.xxx:port/somewsdl?wsdl".

(Microsoft.BizTalk.Adapter.Wcf.Consuming.MetadataExchange.MetadataExchangeException) Unable to download metadata from "http://xxx.xxx.xxx.xxx:port/somewsdl??wsdl" using WS-Metadata Exchange.
(System.InvalidOperationException) Metadata contains a reference that cannot be resolved: 'http://xxx.xxx.xxx.xxx:port/somewsdl??wsdl'. (System.ServiceModel.CommunicationException) 
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error. 

web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\somedll.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
    </system.webServer>
  </location>
</configuration>

When I tested wsdl from SoapUI, it works. Can you help me please?

VS 2010 Ultimate version 10.0.30319.1
BizTalk Server 2010 version 3.9.469.0

I did a test to make sure it wasn't a problem with the old VS / BizTalk:
VS 2015 Professional
BizTalk Server 2016

-------------- Edited ---------------------

I am adding a reference by using:

When I am using "Metadata files" in "BizTalk WCF service consuming wizard" then I get error:

Problem was in wsdl.

Answer 2

Try to browse you WSDL file from the browser, save it locally.And on the WCF Service Consuming Wizard choose the downloaded wsdl file. It should works. have a lConsume web service using Wcf-basichttp adapter
