@copilot can we generate a github action build and verify the build on PRs

Added a GitHub Actions build workflow in commit cdab28c. The workflow triggers on PRs and pushes to main, sets up .NET 10, restores dependencies, and builds the solution in Release configuration.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• aspire.dev
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot the nuget packages are wrong, check the nuget mcp server

Fixed in commit 830ee49. Corrected the package versions:

• Microsoft.Extensions.ServiceDiscovery: 13.1.0 → 10.1.0
• Updated AppHost to use the new Aspire 13.1 SDK format: Sdk="Aspire.AppHost.Sdk/13.1.0" (removed explicit Aspire.Hosting.AppHost package reference as it's now included by the SDK)
