Bump TCGC to 0.72.0 and it's related dependencies for the http-client-csharp package. Rerun Generate.ps1 and ensure all existing tests pass.

Warning

Firewall blocked 4 domains

The following domains were blocked by the firewall during workflow execution:

• api.github.com
• github.com
• raw.githubusercontent.com
• registry.npmjs.org

[!TIP]
api.github.com is blocked because GitHub API access uses the built-in GitHub tools by default. Instead of adding api.github.com to network.allowed, use tools.github.mode: gh-proxy for direct pre-authenticated GitHub CLI access without requiring network access to api.github.com:

tools:
  github:
    mode: gh-proxy

See GitHub Tools for more information on gh-proxy mode.

To allow these domains, add them to the network.allowed list in your workflow frontmatter:

network:
  allowed:
    - defaults
    - "api.github.com"
    - "github.com"
    - "raw.githubusercontent.com"
    - "registry.npmjs.org"

See Network Configuration for more information.
