No xml:base attribute in service node of nuget endpoint response

[pero.p]

Hitting a nuget feed endpoint in proget returns the following:

<service xmlns="http://www.w3.org/2007/app">
   <workspace>
      <title xmlns="http://www.w3.org/2005/Atom">Default</title>
          <collection href="Packages">
               <title xmlns="http://www.w3.org/2005/Atom">Packages</title>
          </collection>
    </workspace>
</service>

The root node, service, contains no xml:base attribute which is seen in other v2 endpoints, e.g. https://www.nuget.org/api/v2:

<service xmlns="http://www.w3.org/2007/app" xmlns:atom="http://www.w3.org/2005/Atom" xml:base="https://www.nuget.org/api/v2">

It appears Dependabot uses the base attribute to build it's list of nuget sources from nuget.configs. As a result of the ProGet not returning a base attribute in the response Dependabot is not able to query the feed for updates to packages.

Is there a reason this attribute is not set? I see there is a Web.BaseUrl config setting in ProGet's advanced settings so I was wondering if setting this would result in the attribute showing up?

Thanks

I can't say why it's like that, probably because NuGet.org didn't have it a long time ago?

One important note; changing this could break a lot of the tools we do support and integrate with --- which include older versions of NuGet client that NuGet.org no longer supports.

Can you bring this up with Dependabot team? It should be a totally trivial fix on their end, and it's not necessary at all for them to use it.

@atripp Thanks for the reply. I submitted a Pull Request myself to the dependabot-core repo.
