Octopus Deploy tool to create nuget packages of your builds.
From Using OctoPack
The easiest way to package your applications from your continuous integration/automated build process is to use OctoPack. OctoPack adds a custom MSBuild target that hooks into the build process of your solution. When enabled, OctoPack will package your Windows Service and ASP.NET applications when MSBuild runs. This makes it easy to integrate OctoPack with your build server - as long as you can pass properties to MSBuild, you can use OctoPack.
