This multi-part tutorial covers the creation of a new data source extension for Power Query. The tutorial is meant to be done sequentially - each lesson builds on the connector created in previous lessons, incrementally adding new capabilities to your connector.
In this lesson, you will:
- Add a TestConnection handler
- Configure the Power BI On-Premises Data Gateway (Personal mode)
- Test scheduled refresh through the Power BI service
