I'm looking for a NuGet package promotion workflow for NuGet packages hosted on an private Artifactory repository. This new feature could be similar to the Maven/Ivy release management functionality. It must be possible to promote a nuget package from a TeamCity build step.
Similar feature description found in MyGet http://docs.myget.org/docs/reference/upstream-sources: "_Many development teams are using some kind of package promotion workflow: pushing a package from one feed to another based on quality gates, target audience, or any other criteria. This is very typical scenario for which upstream sources are essential.
Of course, all of this can happen in an automated fashion using package manager client. However, as promoting a package typically involves some kind of human intervention (e.g. release manager approval), we've also made it a first-class feature in the MyGet web site.
Simply pick the package version you want to promote from the package details page, and hit the Push button to initiate the package promotion flow._"
