Having successfully added NuGet pack  and  push tasks to my Build within VSTS, the next task was to separate out the push from the Build and use it within a Release. The main reason for this is to provide greater control over when a package is pushed to the VSTS package manager rather than after each build.

The first modification is to the Build definition to remove the NuGet push task. Next, I created a new Release definition with a single environment I called Package Manager. The Release definition contained one task and that was the NuGet push command. Since we had already created the package as part of the Build, the path to the NuGet package(s) to publish is available for us to select.

Two points worth mentioning here.

• The path uses *.nupkg to ensure the Release picks up the latest build of the package and not a specific version.
• The path, …/Model-Packaged/… is an Artifact source alias defined in the Artifacts tab.
• 

Once the Release environment has been created with the Push task pointing to our pre-existing Target feed we can create a release which will pick up the current NuGet package generated during the Build and push it into the feed in the Package Manager. One other point to remember is that the push will fail if you try to upload a package to feed with the same version number as the current package.
