Update create .NET console app tutorial series to include sign-file apps with Codespaces

[meaghanlewis]

Summary

This pull request updates the .NET console application tutorials to provide dedicated instructions for both Visual Studio Code and GitHub Codespaces environments. The changes introduce content pivots throughout the tutorials, ensuring users receive environment-specific guidance, code snippets, screenshots, and commands. Additionally, the tutorials are updated for clarity, accuracy, and the latest recommended practices.

Environment-specific guidance and pivots:

• Added zone_pivot_groups: code-editor-set-one metadata and content pivots throughout the tutorials to distinguish steps for Visual Studio Code and GitHub Codespaces users. Each environment now has tailored instructions, prerequisites, and screenshots. [1] [2] [3]

Codespaces-specific instructions and assets:

• Introduced Codespaces-specific steps for creating, debugging, and publishing .NET console apps, including new screenshots, file navigation, and terminal commands (e.g., publishing with dotnet publish HelloWorld.cs and inspecting output in the artifacts/HelloWorld directory). [1] [2] [3] [4] [5] [6] [7]

Content and instructional improvements:

• Updated and clarified step-by-step instructions for debugging (e.g., setting breakpoints, stepping through code, and using the Debug Console), publishing, and running apps, ensuring accuracy for both environments and improving the flow of the tutorials. [1] [2] [3] [4]
• Added a Codespaces-specific cleanup section to guide users on deleting unused Codespaces.

Sample code and assets:

• Added a new HelloWorld.cs sample file with clear code regions to illustrate the main method and output for the tutorials.
• Updated screenshots and image references to match the respective environment (e.g., Codespaces vs. VS Code). [1] [2]

Metadata and date updates:

• Updated metadata fields such as ms.date to reflect the latest revision dates. [1] [2] [3]

These changes ensure that users following the tutorials have a clear, accurate, and environment-appropriate learning experience, whether they're using Visual Studio Code locally or GitHub Codespaces in the cloud.
