Tests whether the gh-aw agent sandbox can run dotnet build. Expected results: - api.nuget.org may be blocked by AWF firewall (now allowlisted via 'dotnet' network) - dotnet CLI may or may not be installed in the container - TOKEN env vars are visible to subprocesses (via --env-all) Changes: - Add pull_request_target trigger for auto-runs on test file changes - Add bash tools (dotnet, pwsh, gh, etc.) to agent - Add dotnet network allowlist (nuget.org, dotnet.microsoft.com, etc.) - Add build experiment section to agent prompt Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Switch from HostApp (needs android workload) to Core.UnitTests (net10.0 only) - Add curl, sed, awk, mkdir, cp to bash tool allowlist - Add workload list check to experiment Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Remove env/TOKEN check (triggered security scanner) - Remove curl test (blocked at tool level) - Add Part A: dotnet new console + build (no workloads needed) - Add Part B: test NuGet network via dotnet restore - Add Part C: try dotnet workload install maui-android - Add Part D: if workloads work, build Core.UnitTests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Copy /usr/share/dotnet to /tmp/dotnet-local (writable) - Set DOTNET_ROOT to writable copy - Try dotnet workload install maui-android - If successful, build Core.UnitTests with workloads available Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Add 'Provision .NET SDK with MAUI workloads' step that runs ./build.sh --target=dotnet and --target=dotnet-local-workloads on the runner BEFORE the agent container starts - .dotnet/ directory is in workspace (mounted into container) - Agent uses .dotnet/dotnet instead of system dotnet - Simplified experiment: restore, build, test Core.UnitTests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Use 'dotnet cake --target=dotnet-local-workloads' instead of 'build.sh --target=dotnet-local-workloads' (Arcade doesn't know Cake targets) - Verify packs/ directory is populated after install - Agent uses system dotnet with DOTNET_ROOT pointing to .dotnet/ (can't execute .dotnet/dotnet due to container noexec) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…oad install - Run 'dotnet tool restore' first to get dotnet-cake - Run 'dotnet cake --target=dotnet' to provision .dotnet/ SDK - Run '.dotnet/dotnet workload install maui-android' directly (bypasses broken Cake dotnet-local-workloads target) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…tion Gradle wrapper failed because ~/.gradle/ is not writable in the agent container. Set GRADLE_USER_HOME to workspace .gradle-home/. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Remove pre-agent provisioning step entirely. The agent now: 1. dotnet tool restore (get dotnet-cake) 2. dotnet cake --target=dotnet (download SDK to .dotnet/) 3. DOTNET_ROOT=.dotnet/ + dotnet workload install maui-android 4. dotnet build Microsoft.Maui.BuildTasks.slnf 5. GRADLE_USER_HOME=.gradle-home/ + dotnet build HostApp Testing whether the entire chain works inside the container. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Add services.gradle.org and downloads.gradle.org - Use dotnet cake --target=dotnet-local-workloads (works in sandbox) instead of dotnet workload install (blocked by read-only /usr/share) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

AWF squid proxy blocks Gradle CONNECT tunneling even with services.gradle.org allowlisted. Work around by downloading Gradle 8.13 zip in a steps: block (no proxy) and caching at .gradle-home/ which is mounted into the container. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
🧪 Build Experiment ResultsAll steps completed. Here are the full results from the MAUI build chain experiment inside the gh-aw agent container: Step A: Provision SDK inside the containerA1: Restore dotnet tools ✅ A2: Download local SDK via Cake ✅ A3: Set DOTNET_ROOT ✅
Step B: Install workloads via CakeB1: Install workloads via Cake ✅ B2: Verify packs ✅ Step C: Build MAUI infrastructureC1: Verify Gradle cache ✅ C2: Build MSBuild tasks ✅ (after fix — see note below)
Step D: Build HostAppD1: Find HostApp ✅ D2: Restore HostApp ✅ D3: Build HostApp for Android (net10.0-android, Debug) ✅ Summary
🎉 The entire MAUI build chain works inside the gh-aw agent container. Key requirements for reliable builds:
Caution Security scanning requires review for Evaluate PR Tests DetailsPotential security threats were detected in the agent output. The workflow output should be reviewed before merging. Review the workflow run logs for details. Warning The following domains were blocked by the firewall during workflow execution:

Replace Cake-based SDK provisioning (runs repo code) with dotnet-install.sh from Microsoft CDN (no repo code executed). Security improvement: steps: block now only runs trusted external tools — dotnet-install.sh, dotnet workload install, curl for Gradle. The only repo data read is global.json's version string (passive). All build commands (BuildTasks, HostApp) still run inside the sandboxed agent container where GITHUB_TOKEN is scrubbed. Changes: - Download SDK via dotnet-install.sh (Microsoft CDN) - Install maui-android workload via dotnet workload install - Compute Gradle hash dir dynamically (base36 of MD5(url)) - Place Gradle zip + .ok marker in correct wrapper cache path - Simplify agent prompt: just verify + build (no provisioning) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
