VSO NuGet Publisher Build Step Fails

Question

I am using Visual Studio Online - Package Manager Preview, along with the new build system. The package manager preview adds a number of build steps, including a \"NuGet Pub

Answer 1

The in-box NuGet Publish task has two options: "external" feeds and "internal" feeds. External feeds are intended for 3rd party services like NuGet.org, Artifactory, and expect a service connection with an API key.

Internal feeds are those hosted by Team Services. Instead of a service connection, you add the URL of the feed's NuGet endpoint. The build system relies on the Project Collection Build Service (for collection-scoped build definitions) or Project Build Service (for "this project"-scoped build defs) being a Reader or Contributor to the feed. Docs for all that are available here.
