preview mode, you are able to set up feeds and then publish NuGet packages either through NuGet command line or as a step in a Visual Studio build. I’m going to assume you’ve read the documentation and set up a feed, and that as part of your build you wish to publish a NuGet package to your new feed, and then you want to add the feed as a service on Octopus. I’m also going to assume you are using the NuGet package step instead of OctoPack to make your NuGet packages.
