Overview
Activity
Update the Zoo project to checkpoint 2.6.
User Story
As a developer, I want to complete the Zoo 2.6 checkpoint so the project includes the required programming concepts and behavior.
Acceptance Criteria
- Existing files contain the checkpoint changes shown in this walkthrough.
- The solution builds successfully.
- The application starts and the updated behavior can be exercised.
- Names, casing, namespaces, and member signatures match the checkpoint source.
Task List
- Update 13 existing source files.
- Build the solution and resolve any compiler errors.
- Run the application and verify the new behavior.
Exact Casing Matters
Use the filenames, class names, namespaces, method names, property names, and enum values exactly as shown.
Watch Out For
Do not copy build-output folders such as bin, obj, .vs, or package caches into your working project.
Before You Begin
Start with a clean copy of Zoo 2.5 End. Rename the extracted solution folder and solution file for the current checkpoint before making code changes.
