Part 07: Debugging with Copilot

In this section, you'll learn how to use Copilot to debug an exception in your application.

  1. [] Debug the AppHost project if it isn't yet, and open the store from the .NET Aspire dashboard.

  2. [] Click on the Go to About button in the navigation menu.

  3. [] Observe that an exception occurs, and the application crashes.

  4. [] Press the Analyze with Copilot option in the pop up.

  5. [] Review how Copilot brings in debugger information, including stack traces and variable states.

  6. [] Note how Copilot recommends a fix for the issue or provides code suggestions to resolve it.

Key Takeaway: Copilot can assist in diagnosing and fixing exceptions by analyzing debugger information and providing actionable recommendations.

Using Watch Windows and Visualizers

In this subsection, you'll learn how to use Copilot to analyze variables using watch windows and visualizers.

  1. [] Open the Products.razor file again from the Products project.

  2. [] Add a breakpoint at the end of the OnInitializedAsync method.

  3. [] Debug the TinyShop.AppHost and open the store from the .NET Aspire dashboard, and navigate to the Products page.

  4. [] When the breakpoint is hit, hover over the imagePrefix variable.

  5. [] Press the Copilot button to analyze the imagePrefix variable.

    Note: you can also see these in the Locals or watch windows

  6. [] Observe how Copilot provides detailed information about the variable, including its value and potential issues.

  7. [] Hover over the products collection and click the View button with the magnifier icon.

  8. [] Use the visualizer to inspect the contents of the products collection.

  9. [] Click the Generate expression button and, in natural language, type: Products that have the name outdoor in them and are under 40 dollars

  10. [] Observe how Copilot generates the appropriate expression automatically.
