We asked GitLab Duo Chat how to start a new C# project and learned how to use the dotnet CLI. The first Code Suggestions challenge is not tiny - query the GitLab REST API and print the response. The code works -- we asked Chat for help with .gitignore and CI/CD configuration for C#. The CI/CD jobs fail, and Root Cause Analysis helps out. Next, we explore code tasks and let Chat /explain the REST API calls in the source code. To create tests later, we ask GitLab Duo to /refactor the selected code into a function. We refined the prompt to `/refactor into the public class` to get code that can be accessed from the test project. The code gets /tests generated using a code task in Duo Chat. We also learned that C# solutions should contain the application and test project side-by-side to avoid import inception problems. After solving them, we added more tests with the help of code suggestions. The coffee chat concludes with running tests in CI/CD …...more
