We have a private NuGet server and my issue is the TFS 2017 builds don't recognize the internal package's NuGet server, obviously, without specifying the URL. I've tried putting it in Nuget.config and it worked, but with some issues.
What I would like to do, however, is somehow add this to the global list of feeds. I do not have NuGet installed on the server, though NuGet restore is happening as a build Task, so it exists under c:_work_tasks\NuGetInstaller_333b11bd-d341-40d9-afcf-b32d5ce6f23b\0.2.21\ etc, and do not see anything that would let me change the set of feeds.
BTW, when I added a package source to nuget.config, it seemed to ONLY download from that source and ignored all the defaults, such as nuget.org, etc.
How can I add an internal nuget server so that all my builds natively can access it? Thanks.
