If you are using Visual Studio Team Services (VSTS) (formerly VSO) or an on-premises Team Foundation Server (TFS) 2015 Update 2 (or newer) you can use the open-source extension for Octopus available in the VSTS marketplace.
Using this extension you can:
- Package your built application
- Push those packages to the Octopus built-in repository
- Create releases and deploy them to your environments
