Publishing NuGet package for NetStandard 1.6 library

We have developed a .NET Core library that targets NetStandard 1.6.  We are successfully building and packaging the library using the 'dotnet pack' runner type/command combination.  And, we have configured the artifact paths sufficiently that the output of the build/pack is appearing as an artifact for the project.  But, when we browse NuGet packages in Visual Studio using TeamCity as the source, the package does not appear.  (We browse the NuGet packages from a NetStandard 1.6 project to ensure compatibility.)

Here’s a typical build log.  Notice that the package is being created, and published (the last three lines).

Is there something else we need to do?
