Who it is for

For everyone after K2 whose employer is introducing Copilot or already has, and who must use it in a verifiable way that respects data protection.

Prerequisites

K2 (C#, Git and pull requests, tests with xUnit) or the placement test. The exercises need a GitHub account with Copilot access; which plan applies is for your administration to say.

Afterward, you can

  • Tell the forms of Copilot apart and explain which data goes where
  • Write prompts and context that produce usable code
  • Use agent mode, the command line and MCP with approval and judgment
  • Write instruction files and review generated code and generated tests like someone else's code
  • Draft exclusions and prompt rules for a team and name the questions the data protection office will ask
