We build connectors for a wide variety of solutions for partners using .Net technology, all based on the principle of minimizing changes to standard functionality.
Taking our own medicine, we chose a cloud-based task management system (Jira Atlassian) and a solid connector from there to NAV. In the process of securing better version control in our continuous delivery models, we also built a connector from Jira to TFS.
In recent years, some of our partners have asked for help setting up similar systems. We will be pleased to help you with a more robust development setup structure, and we will gladly share best practices with you, as this enables us to improve tools and methods for ourselves as well.
